Interactive Voice Response in University of Management & Technology
Abstract
Interactive voice response (IVR) systems have been around for some
time to help guide customers to appropriate business units or
information. However, with the use of Internet technologies and
wireless phones on the rise, coupled with the rapid development in
the speech recognition and speech synthesis technologies, new doors
for voice technology are opening to test demand in the marketplace.
Whats more convenient than picking up a phone? One can have
instant access to the information needed to make business operate
more efficiently. Many businesses are betting that consumers will
embrace any technology that provides real-time access to
information piped through their regular telephone, wireless phone or
voice-connected handheld device.
A system in which the input and/or output are through a spoken,
rather than a graphical, user interface is what we call as Interactive
voice response system or simply IVR system. The web has made it
possible to access information at the click of the mouse. In recent
years the meaning of what a client has grown from the desktop
computers to other clients like phones and mobile pieces. This is
where voice control came in.
Analyzing the requirements of the need for implementing the voice
systems, our dissertation work concentrate on proposal of
implementing an interactive voice response in University of
Management and Technology. At the client side it consists of a
telephone or cell phone connected to a Public Switching Telephone
Network. In the middle tier it consists of voice server equipped with
VoIP gateway, which facilitate the users of PSTN to connect to the
voice application that works in the IP network. This voice server

identifies the call made by users of telephone network, initiates the
voice application, presents the user with the required information and
terminates the call when the user wants to exit from the application.
Database server stores the information of an enterprise or institute in
terms of tables where one can store the necessary information to
present it to users. It can be used with any phone at anywhere. One
can dont have to put up with entering data using tiny keypad, but
rather one can interact with the service in a very natural manner.
The dissertation work aims at suggesting the implementation of an
IVR system for UMT. It promises a good speech interface to make the
user feel comfortable to interact with the system.

2What is an IVR?
2.1Introduction to IVRThe blueprint for IVR began in 1941, when the Bell System developed a newtone dialing methodology. Bell unveiled the first telephone that could dial areacodes using DTMF technology at the Seattle World Fair in 1962. DTMFtelephones enabled the use of inband signaling, i.e., they transmit digitalcodes in the same 300 Hz to 3 kHz range occupied by the human voice.
Despite the fact that more companies began using the system in the 1970s toautomate tasks in call centers, the technology was still costly and complicatedwhich made for low market penetration. However, by the 1980s a number ofnew competitors entered the market and uptake of IVR technology started toincrease.
When call centers began to migrate to multimedia contact centers in the late90's, companies began to invest in Web-enablement and Computer TelephonyIntegration (CTI) with IVR systems. IVR became vital for call centers deployinguniversal queuing and routing solutions and acted as an agent which collectedcustomer data to enable intelligent routing decisions.
Having remained technologically static since its development in the 1980s,speech recognition started to become more common and cheaper to deploy.This was due to increased Computer Processing Power and the migration ofSpeech applications from propriety code to the VXML standard. Theintroduction of the VXML standard also simplified the integration process
between IVR systems and any back end hosts.
IVR technology is one that is related to the masses in general or can affectthe masses on a larger scale. This technology can dramatically improve theefficiency and productivity of the Universitys administrative personnel whileproviding a flexible and cost-effective service to students/parents.
Giving information to university students, Institute scholars, informationabout progress of student to Parents is one such problem.
2.2Typical Types ofIVRVoice applications will typically fall
into one of the following categories.Queries and Transactions.
Queries: In this scenario, acustomer, who can be a student or a

parent, calls into a system to retrieve information from a Web-basedinfrastructure. The system guides the customer through a series of menus andforms by playing instructions, prompts, and menu choices using prerecordedaudio files or synthesized speech. The customer uses DTMF input to makemenu selections and fill in form fields. Based on the customers input, thesystem locates the appropriate records in a back-end enterprise database. The
system presents the desired information to the customer; either by playingback prerecorded audio files or by synthesizing speech based on the dataretrieved from the database.
Examples of this type of self-service interaction include applicationsproviding status reports, course registered, courses offered, result of thestudent, event listings, admission dates, last date for form submission andcustomer service information.
Transactions:In this scenario, a customer, who can be a student ora parent, calls into a system to execute specific transactions with a Web-basedback-end database. The system guides the customer to provide the data
required for the transaction by playing instructions, prompts, and menuchoices using prerecorded audio files or synthesized speech. The customerresponds using DTMF input.
Based on the customers input, the system conducts the transaction andupdates the appropriate records in a back-end enterprise database. Typicallythe system also reports back to the customer, either by playing prerecordedaudio files on the information in the database records. Examples of this type ofself-service interaction include applications Fee submission, financialtransactions, fine imposed, calendar appointments, electronic relationshipmanagement (ERM) and order management.
IVR = Interactive Voice ResponseGeneral term for any computerized, automated telephone system.Historically used to refer to touch-tone systems, IVR has evolved to includeboth touch-tone and speech-recognition based systems.
Caller InputTouch-Tone, a.k.a., DTMF (Dual-Tone Multi-Frequency)Speech Recognition, a.k.a., ASR (Automated Speech Recognition)
System ResponseTTS (Text-to-Speech) Digitized voice typically used to play back dynamic
information to callers. Recorded Audio
(e.g., .wav files) Pre-recorded sound files for play back of static information;or, when stitched together, can be used to play back dynamic information.
Objective

Interactive Voice Response in University of Management & Technology
The goal of a good IVR application is to connect callers with the informationthey are seeking as quickly and as efficiently as possible, which may meaneither a fully automated response to the callers inquiry, or connecting thecaller to the most appropriate live agent.
1.1Typical usesIVR systems are typically used to service high call volumes, reduce cost andimprove the customer experience. Examples of typical IVR applications aretelephone banking, televoting, and credit card transactions. Large companiesuse IVR services to extend the business hours of operation.
Call centers use IVR systems to identify and segment callers. The ability toidentify customers allows the ability to tailor services according to thecustomer profile. It also allows the option of choosing automated services.Information can be fed to the caller allowing choices such as: wait in thequeue, choose an automated service, or request a callback (at a suitable time
and telephone number).
The use of CTI will allow the IVR system to look up the caller line identification(CLI) on a network database and identify the caller. This is currently accuratefor about 80% of inbound calls. In the cases where CLI is withheld orunavailable, the caller can be asked to identify themselves by other methodssuch as a PIN or password. The use of DNIS will ensure that the correctapplication and language is executed by the IVR system.
CTI allows a contact center or organization to gather information about thecaller as a means of directing their inquiry to an appropriate agent. CTI canalso extract important or relevant information about the individual customer
from the database, making for a more effective and efficient service.The use of IVR and voice automation enables a company to improve itscustomer service and lower its costs, due to the fact that callers' queries canbe resolved without the cost of a live agent who, in turn, can be directed todeal with specific areas of the service. If the caller does not find theinformation they need, or require further assistance, the call is thentransferred to an agent who can deal with them directly through CTIintegration. This makes for a more efficient system in which agents have moretime to deal with complex interactions, for example, customer retention, upselling, cross selling and issue resolution.
This way, the customer is more likely to be satisfied with a personalizedservice and the interaction is likely to be more fulfilling and rewarding for theagent, as opposed to dealing with basic inquiries that require yes/noresponses, such as obtaining customer details. Employee satisfaction isimportant in the telecommunications industry due to the fast turnover of staff,IVR is therefore one way of retaining a workforce and allowing them to do amore effective job.

IVR also enables customer prioritization. In a system wherein individualcustomers may have a different status the service will automatically prioritizethe individual's call and move prime customers to the front of the callingqueue.
Finally, IVR may be used by survey organizations for asking more sensitivequestions where the investigators are concerned that a respondent might feelless comfortable providing these answers to a human interlocutor (such asquestions about class, teacher etc). In some cases an IVR system can be usedin the same survey in conjunction with a human interviewer. For example,during the survey the interviewer might inform the respondent that for thenext series of questions they will be sent to an IVR system to continue orcomplete the interview.
1.2Voice-activated dialersVoice-Activated Dialer (VAD) IVR systems are now used to replace theswitchboard or PABX (Private Automatic Branch exchange) operators and are
used in many hospitals and large businesses to reduce the caller waiting time.An additional function is the ability to allow external callers to page hospitalstaff and transfer the inbound call to the paged person.
1.3Entertainment and informationThe largest installed IVR platforms are used for applications such as tele-voting on television game shows, which can generate enormous call spikes.Often, the network provider will have to deploy call gapping in the publicnetwork to prevent network overload.
The following are some of the more common uses of an IVR:
Mobile Pay-As-You-Go account funding
Telephone banking balance, payments, and transfers
Mobile purchases particularly for mobile content, such as ring tonesand logos
Caller identification and routing
Order placements credit card payments
Airline ticket booking, flight arrivals, flight departures, check-in
Adult entertainment dating, chat line, etc.

Answered by voice mail or answering machine (In this circumstancesthey can leave a message)
Fax tone (IVR can leave a TIFF image fax message)
Answer (IVR can tell the customer who is calling and ask them to wait foran agent)
Recognize divert messages and abandon call.
IVR uses Call Progress Detection to monitor line conditions, and report to theIVR database.
1.1How users can access the IVRapplication?
Once the voice applications are deployed, users simply dial the telephonenumber that the user provide and are connected to the corresponding voice
application. Answer the telephone call Play a prompt Wait for the callersresponse Take action as directed by the caller Complete the interaction
(i). A user dials the telephone number provided to the application. The IVRanswers the call and executes the application referenced by the dialedphone number.
(ii). The IVR plays a greeting to the caller and prompts the caller to indicatewhat information he or she wants. The application can use prerecordedgreetings andPrompts or synthesize them from text.
(iii). The application waits for the callers response for a set period of time.The caller can respond by pressing one or more keys on a DTMF telephoneKeypad, depending on the types of responses expected by the application.If the response does not match the criteria defined by the application (suchas the specific digits), the voice application can prompt the caller to enterthe response again, using the same or different wording.
(iv). The application takes whatever action is appropriate to the callersresponse. For example, the application might update information in adatabase, retrieve information from a database and speak it to the caller. It
also involves store or retrieve a voice message, launch another application,Play a help message after taking action, the application prompts the callerwith what to do next.
(v). The caller or the application can terminate the call. For example, thecaller can terminate the interaction at any time, simply by hanging up; theIVR can detect if the caller hangs up and can disconnect itself. If theapplication permits, the caller can use a command to explicitly indicate that

2Calls in UMT
2.1Problem DefinitionUntil recently, the World Wide Web has relied exclusively on visualinterfaces to deliver information and services to users via computersequipped with a monitor, keyboard, and pointing device. In doing so, a hugepotential customer base has been ignored: people who (due to time,location, and/or cost constraints) do not have access to a computer.
Many of these people do, however, have access to a telephone. Providingconversational access (that is, spoken input and audio output over atelephone) to Web-based data will permit companies to reach this untappedmarket.
Users benefit from the convenience of using the mobile Internet for self-service transactions, while companies enjoy the Webs relatively lowtransaction costs. And, unlike that rely on dual tone multi-frequency (DTMF)(telephone key press) input, IVR applications can be used in a hands-free oreyes-free environment, as well as by customers with rotary pulse telephoneservice or telephones in which the keypad is on the handset
Even though you made the website perfectly dynamic using manytechnologies, users cannot feel it more comfortable as it requires them to sitin a static place before a terminal and access the required information. Butits not possible for mobile users, to perform a transaction or get the desiredinformation through desktops PC. What they want is that they can be able to
do it from anywhere through any network like PSTN, Internet, mobilenetwork.

1Working of IVRs
1.1How IVR works?
IVR System allows clients (here client is parents/students/schooladministration/school finance department) to make calls over atelephone line through toll free numbers or dedicated direct linesthereby enabling the Service providers/School administration/Instituteauthorities to provide relevant information over the same telephone lineto their clients.
The IVR system is a computer program that allows interactive sessionswith students/parents without a teacher having to be present or acts as
a reporting tool for finance department without any manual/paper work.
IVR interacts with the caller to determine (via collection of rollnumber/registration id of student or special pin entered by caller orcombination of both) who is calling and the reason for the call.
The IVR can also provide automated services to the caller i.e.information on University forthcoming events etc.
The IVR acts as a play-and-collect box where the only call routing logicthat exists is to provide fall back routing capability.
The IVR performs a database lookup based upon the collected uniqueroll number/registration number and passes the data to database bywhich caller can listen real time data e.g. exam results, any fineimposed on childrens etc.

IVR applications can be built for multiple functionalities which is not limitedto
Homework assignment helpline Pay University fees through credit/debit cards University information on forthcoming events - allows parents access to
the latest university activities more conveniently Exam schedules Exam results
Offer details of courses/subjects offered in university Talk to teachers/lecturers Self study/evaluation
IVR systems are especially useful in case of call centers to respond tothe customers in voice and transfer the calls to other informationsystems.
Interactive Voice Response (IVR) system enabled World Wide Websites(internet) make the information reachable even to telephones and cell phones. This facilitates the user to get the information easily by just dialing theparticular server using their handsets at any time round the clock.
Interactive Voice Response (IVR) applications enable callers to query andmodify database information over their telephone by dialing digits on theirtelephone. Callers can use their touch-tone pad to input requests, such asregistering for a course, obtaining a course schedule, or requesting Feebalance information and the database speaks information back to the caller-using Text-to-Speech.
IVR offers customers and businesses a new level of freedom by enabling themto conduct transactions 24 hours a day, seven days a week. Businesses of allsizes are realizing the tremendous benefits of IVR applications for their callprocessing and information delivery needs. IVR functionality links a phone
system to a database to provide customers with 24-hour immediate access toaccount information, via telephone.
To ensure security IVR can be set up to allow the caller access to accountinformation only if the caller enters a valid account number and correspondingpersonal identification number.
IVR allows full connectivity to the most popular databases including MicrosoftAccess, Microsoft Excel, Microsoft Fox Pro, DBase. One can read information

from, and write information to, databases, as well as make a query databasesand can return information.
The application files can reside on the local system, an intranet, or theInternet. Users can access the deployed applications anytime, anywhere, from
any telephony-capable device, and you can design the applications to restrictaccess only to thosewho are authorized toreceive it.
1.1
Technologies usedDTMF signals (entered via the telephone keypad) and natural languagespeech
recognition interpret the caller's response to voice prompts.
An IVR can be utilized in several different ways:
1. Equipment installed on the customer premise
2. Equipment installed in the PSTN (Public Switched Telephone Network)
3. Application service provider (ASP).
4. Hosted IVR

A simple voice mail system is different from IVR in that it is person-to-person,whereas an IVR is person to computer. IVR voice forms can be used to providea more complex voice mail experience to the caller. For example, the IVRcould ask if the caller wishes to hear, edit, forward or remove a message thatwas just recorded.
An automatic call distributor (ACD) is often the first point of contact whencalling many larger businesses. An ACD uses digital storage devices to playgreetings or announcements, but typically routes a caller without promptingfor input. An IVR can play announcements and request an input from thecaller.
This information can be used to profile the caller and route the call to an agentwith a particular skill set. (A skill set is a function applied to a group of call-center agents with a particular skill.)
Interactive voice response can be used to front-end a call center operation byidentifying the needs of the caller. Information can be obtained from the callersuch as account numbers. Answers to simple questions such as account
balances or pre-recorded information can be provided without operatorintervention.
Account numbers from the IVR are often compared to caller ID data forsecurity reasons and additional IVR responses are required if the caller ID datado not match the account record.
IVR call flows are created in a variety of ways. A traditional IVR dependedupon proprietary programming or scripting languages, whereas modern IVRapplications are structured similar to Web pages, using Voice XML[2], CCXML[3],SRGS[4], SALT or T-XML languages.
The ability to use XML developed applications allows a Web server to act as anapplication server, freeing the developer to focus on the call flow. It waswidely believed that developers would no longer require specializedprogramming skills, however this has been proven to be misguided as IVRapplications need to understand the human reaction to the application dialog.This is the difference between a good user experience and IVR hell.
Higher level IVR development tools are available in recent years to furthersimplify the application development process. A call flow diagram can bedrawn with a GUI tool and the application code (Voice XML or SALT) can beautomatically generated.
In addition, these tools normally provide extension mechanisms for software
integration, such as HTTP interface to Web site andJava interface forconnecting to a database.
In telecommunications, an audio response unit (ARU) is a device thatprovides synthesized voice responses to DTMF key presses by processing callsbased on (a) the call-originator input, (b) information received from adatabase, and (c) information in the incoming call, such as the time of day.

2Requirements of an IVR-To deliver or leverage IVR, an enterprise requires following
2.1IVR PlatformsIVR platforms are the "server and operating system" hardware and softwareplatforms on which IVR solutions run.
IVR platforms at a minimum provide the ability to play and record prompts andgather touch-tone input. IVR platforms may also offer the ability to recognizespoken input from callers (voice recognition), translate text into spoken outputfor callers (text-to-speech), and transfer IVR calls to any telephone or callcenter agent.
2.2IVR ApplicationsIVR applications are programs that control and respond to calls on the IVRplatform. IVR applications can either be developed by an enterprise, by an IVRdevelopment shop, or by companies that offer canned IVR applications.
IVR applications direct the IVR platform to prompt callers, gather input, andtransfer callers to other phones. IVR applications also call on existing back-enddatabase and application servers to retrieve records and information requiredduring the course of a call.
2.3Back-end serversBack-end servers are existing enterprise servers on which the requiredcustomer or corporate data can be found.
Back-end servers can include databases, mainframes, Java or other applicationservers, and third party information services and solutions.
2.4Telephony InfrastructureTelephony infrastructure includes telephone lines, call switching equipment,and call center Automatic Call Distributors (ACDs).
Telephone lines for IVR can be standard analog lines, digital T1, or digital ISDNlines. These lines are connected on one side to the IVR platform and, on theother, to call switching equipment including Telco switches, Voice over IPgateways, and corporate PBX's; or in some cases, directly to call centers viaan ACD.

2.5IVR ExpertsIVR Experts include employees and consultants who know IVR technology andchallenges well.
Ideally, IVR teams should include one or more members who have experiencewith IVR integration, configuration, reliability and redundancy, applicationdevelopment, and IVR solution deployment management.
2.6Weighing the OptionsThere are a number of options to consider when designing and implementingan IVR system:
Hosted vs. On-Premise Speech Recognition vs. Touch-Tone Outsourcing vs. contact center automation
Automation vs. Live Agents VoIP vs. PSTN Web Self Service vs. Phone Self Service
1.1.1Hosted vs. On-Premise
Figure 6: Hosted Solution
Hosted
Benefits Minimize capital expense and development expense
Leverage outsourcers expertise in speech, telephony, and datacenter operations
Technology upgrades are taken care of by provider
Planning for peak capacity handled by provider
36
-
8/9/2019 Interactive Voice Response System in UMT
37/66
Interactive Voice Response in University of Management & Technology
Tradeoffs
May not be well-suited for very high-volume applications
Control of call infrastructure handed over to provider (but notnecessarily application development or business logic)
Figure 7: On Premise Solution
On-Premise
Benefits
Lower telco cost at very high call volumes
Full control of infrastructure
Tradeoffs
Upfront capital expense
Application development is cumbersome
Requires dedicated operations personnel and facilities
Serving peak capacity can result in inefficient use of resources inoff-peak
Hosted vs. on-premise IVR
With the introduction of Web services into the Contact Center, integration hasbeen simplified. The use of Web based applications allow IVR applications to
be hosted remotely from the contact center. This allows the use of hosted IVRapplications using speech to be made available to smaller Contact Centersacross the globe and is likely to lead to an expansion of ASP (ApplicationService Providers).
IVR applications can also be hosted in the public network, which do notrequire contact center integration. This will include public announcementmessages or message services for small business. It is also possible to use twoprong IVR services where the initial IVR application is used to route the call tothe appropriate contact center. This can be used to balance loading across

multiple contact centers or provide business continuity in the event of systemoutage.
Outsourcing vs. contact center automation
Contact centers are very expensive to run, and can be seen as a drain oncompanies' operations. Contact centers are usually seen as cost centers,
however, the ability to convince customers to buy services and products canreduce operational expenditure.Methods of reducing contact center running costs includeoutsourcing andautomation. Outsourcing to other countries can reduce operationalexpenditure by as much as 30%, however, differences in culture and languagecan prove problematic for customers, whose dissatisfaction can lead tocustomer complaints and loss of business. Also, it is more difficult to sell tocustomers from foreign contact centers.Automation in a contact center can also reduce operational expenditure byaround 30% though the introduction of technologies such as customerprofiling, CTI, and IVR using speech recognition. The use of automation in the
contact center promotes efficiency, allowing contact centers to be located inthe country from which the call is originated. Customer satisfaction can bemonitored by the use of customer survey applications. The information fromsurvey applications can be used to improve customer service.

Multi-Vendor Selection Process
1.1.1Speech Rec. vs. Touch-Tone
Touch-Tone
Navigating an IVR menu tree by pressing numbers on a keypad Benefits
Works reliably when the number of options is limited
More traditional, so there is no learning curve
Better for sensitive information
Easier to develop application
Tradeoffs
Lower automation rates than speech recognition
Difficult to use with a large number of options
Does not handle alphanumerics, names and addresses
Difficult to use in a hands-free environment
Perceived as older, less human technology
Speech Recognition
The ability to navigate an IVR menu tree through voice instead of thekeypad
Benefits
Speech is a necessity when needing a large number of options(states, musical groups, stocks, U.S. Senators)
Capture Name and Address, Alphanumerics
Can be more convenient for callers, such as callers who are driving
Has the wow factor for engaging customers more directly thantouch-tone
Increases automation rates over touch-tone
Tradeoffs
Application development can be more complex (error handling)
May not work well for sensitive information (CC, PIN, Account #s)

1.1.1Automation vs. Live Agent
Automation
Benefits
Per minute costs are much lower
Provides 24*7*365 access to information for all, and ready accessfor callers without web access
Often more efficient than talking to an agent, esp. for repeatcallers
Offers consistent service quality and easily handles repetitivetasks
Often preferred for personal or sensitive information
Tradeoffs
Not as personal as a live agent
Often seen as a barrier by callers
Cannot automate all services required by callers
Live Agents
Benefits
Seen as more customer-friendly callers like talking to agents
More traditional, so frustration levels can be decreased
Agents can handle tasks not possible through automation
Tradeoffs
Costs are much higher when including salaries, benefits, officespace, etc.
Agents perform repetitive tasks, leading to higher turnover
Not consistent callers experience differs by agent
Waiting on hold for a routine task is inefficient for callers
Bottom Line: Automate straightforward tasks and transactions (seePersonalized IVR), but always provide option for live agent

1.1.1VoIP vs. PSTN
VoIP: Voice over Internet Protocol
Benefits
Through associated protocol, SIP (Session Initiation Protocol), datacan be passed along with the call
Can carry phone calls into the IVR and transfer calls out of the IVRto live agents
Typically less expensive than PSTN
Tradeoffs
Call quality can be diminished depending on the bandwidthavailable through the end-to-end connection over the IP network
issues can include delays, static and echoing.
PSTN: Public Switched Telephone Network
Benefits
Consistent high audio quality
Typically already in place at most facilities
Not affected by power outages
Traditional technology that all agents know
Tradeoffs
Difficult to pass additional information along with the call
Typically more expensive than VoIP
1.1.1Web vs. Phone Self Service
Web and Phone self service are complementary channels for providingself service to customers, partners, and employees
Web and Phone can (and should) use the same backend database(s) topower the interaction with visitors and callers
The telephone extends the reach of Web applications, providing on-the-go, convenient access without duplicating infrastructure

2IVR Call flows in UMTWe are proposing following IVR call flows or Voice User Interface (VUI) toaddress issues and problems that are being faced by different departments ofUMT.
1: Admission Department2: Registrar Department3: ASU Department4: Office of Treasurer5: UMT Exchange
2.1Admission Department
This department facing major issues during the admission season when dailythey have to entertain more than 500 calls those are almost consist of similarsort of queries related to admission criteria, program outline, scope, deadlineto submit application, test and interview dates etc.
Currently in this department three persons are working, to handle huge callvolume. They usually stay late night to answers maximum calls but still callabandon rate is 40% during the admission season.
Their job nature becomes very hectic and boring to answers same sort of
question whole day especially during admission season.
We have discussed with them in detail to understand their problems, based ontheir requirements we are proposing an IVR solution following are few benefitsof this:
Call abandon rate can easily be decrease by adding more lines to IVRsolution during admission season.
IVR application can answers all FAQ to the candidates/callers IVR can transfer the call to representative if needed. IVR will be available 24X7 to entertain large numbers of calls around the
clock

1.1Registrar Department
Registrar office is daily receiving 80 to 120 calls per day most of the callers areasking following questions:
Result Declaration Date Fee Matters Status Fine Detail Admission and Financial aid Detail Convocation Dates
In addition to this registrar office also contact with the parents of thosestudents who are getting low CGPA to inform progress report of student.
We are proposing inbound and outbound IVR solution for registrar office thatwill give a relief to registrar office staff because IVR solution will become thefront line agent to answer all FAQ to the caller instead these calls answered bythem and they can focus on their core duties that will defiantly enhance theirmoral and productivity level.
The outbound IVR automatically interact with student database and prepare alist of student those CGAP is not meeting the UMT standard along with theircontact information. After preparing the list outbound IVR will start reachingparents and conveying prerecorded message to them. This would save a lot of
registrar office time because they do not worry to invest time to manuallyprepare a list and reaching or sending reports to parents all this will be doneautomatically by IVR solution.

1.1ASU Department
Typically ASU receiving calls of following nature:
Teacher is not available Students asking for makeup class Time Table Courses offered
All these information is easily provided through IVR system where studentscan simply dial in and retrieve relevant information through system instead tocontact directly with ASU department representative.
Sometime if teacher is not available most of students lodged complaints thatthey were not informed on timely fashion, to address this issue one alternative
solution is outbound IVR that will reach to every student and inform him/herabout the schedule of teacher.

1.1Office of Treasurer
Mostly student calls this department to check the status about their dues thisinformation can easily provided through IVR. In addition to this IVR can playthe history of the account settlements and playback the due dates and
amount of future installments.
On suggestion UMT dues can be paid through IVR by using Credit Card but thisarea requires certifications to ensure the critical nature of data must besecured and to meet the different service provider (vendors) requirements.

1.1Implementation Strategies(suggested)
The proposed solution can be implemented either by deploying the IVR onthird party IVR service provider or developed using free open source Software.We are providing brief detail about both solutions:
1.1.1Implementation of IVR as Hosted Solution
VOXEO
VOXEO one of the leading IVR hosted service provider in the world that is alsoproviding services in Pakistan as well.
For detail information about VOXEO please visit the following site.http://www.voxeo.com/
Benefits of Hosted Solution:
No Telecom H/W Require Easily integrate with existing Infrastructure (desktop/Web base) Provide Local DNIS
Cost Estimation
It would cost $ 0.09 per minute i.e. Rs. 7.56 ($1 = Rs. 84) They will also charge one time setup fee. Annual Local DID/DNIS fee that would be around $200 There should at least buy 500 minutes per month
8.6.2 Software/Hardware Requirements
VOXEO is providing W3C VXML 2.1 based solution i.e. similar model for anyweb base application.
On the Web, browsers make requests -- via internet protocols such as HTTP --to Web servers. These Web servers host both static pages and dynamicapplications which return HTML to the browser. The result is a visual pagethat is viewable in a Web browser.

Figure 9: General Architecture of Browser Base Application
On the Voxeo network, voice applications follow the same browser model asstandard Web pages. Instead of HTML, phone markup (VoiceXML, CCXML, orCallXML) is used to write the page. When processed by the Voxeo VoiceCenternetwork, these pages return audio to the caller.
Figure 10: General Architecture of VXML Base Application
So for hosting solution there is no any specific hardware requirements we canuse the existing Web Server and develop the server side application using anylanguage on which we have expertise.
