Tropo.js Platform✓Tropo.js is the world’s first Communications PaaS

✓Tropo.js Apps • Execute in the core network instead of on devices like smart phones • Listen to subscriber events (incoming calls, outgoing messages, etc.) • Control by recording, forking and ‘mashing up’ live conversations

✓PaaS means that apps auto-scale to meet user demands • Developers can focus on features instead of infrastructure • Carriers maintain end-to-end control over quality of service

Use Cases

Financial Compliance

Record all or part of the call

Lots of Things. One Identity.

Tropo’s Telephony of Things™

✓ Manage communications across all your things. ✓ It’s like magic. Tropo apps use location, social status

and machine data to seamlessly route, share and mash-up live communications.

✓ Single phone number / identity on all devices

✓ All devices ring when calling the mobile number

✓ Presence info on remaining devices allow web and mobile apps to respond to calls in progress

✓ Add new participants or start call recording from any screen!

Media and MRF InteractionTropo.js works best when combined with existing network assets

✓ While Tropo.js ships with a software-based media server, it was designed to leverage existing MRF capabilities like call recording, video conferencing and speech recognition.

✓ A standard Java interfaces called JSR-309 is used to abstract all media operations within the Tropo.js AS, making it possible to integrate and combine network assets from multiple vendors.

✓ e.g. Video Conferencing from Ericsson, Speech Recognition from AT&T Watson

Tropo.js in an IMS Environment✓ The IMS enables a diverse set of endpoints to participate in telco communications by leveraging

Internet protocols to unify the core network and by defining a standard architecture for adding new network services through specialized Applications Servers (AS)

✓ The Tropo.js AS is one such Application Server. When eligible subscribers make and receive calls, their signaling flows through Tropo.js, allowing 3rd party apps to enhance conversations in real-time. This level of control is accomplished through the standardized IMS Service Control protocol (ISC).

✓ When subscribers purchase their first Tropo.js-based app, a special entry is created in the subscriber’s HSS record which instructs the IMS to route future calls and text messages through the Tropo.js AS. This special entry is called an Initial Filter Criteria (IFC). This provisioning step can be done manually by the operators or through an automated system provided by the operators.

✓ Tropo.js does not require direct access to the HSS

Basic IMS Signaling Model• In the basic model, each user is assigned to a Call

Session Control Function (CSCF)

• Conversations flow from one CSCF to the other by interrogating the HSS for routing information

• SIP is used as the standard signaling protocol between the terminals, and the network and also between network elements

IMS w/ Application Server• In addition to basic routing information, the HSS contains

information about enhanced services enabled on the user’s mobile subscription.

• Historically, these services were implemented through complicated a deeply specialized technologies such as CAMEL with no standard model for on-boarding and provisioning new services.

• IMS opted for a simpler model by providing a standard model for provisioning and allowing new services to participate directly in the underlying network signaling. The nodes providing these new services as referred to as IMS Application Servers (AS)

• The HSS maintains and list of Application Servers on behalf of each user with instructions on how to route calls and other network events through them.

• A SIP-based protocol is used between the CSCF and the Applications Servers called ISC. The ISC specifies certain special SIP headers that must be maintained between call legs to preserve core subscriber functions such as billing.

• While the AS model is quite flexible, operators are still faced with the risk and operational overhead of adding network elements for each new service; resulting in missed market opportunities

• Tropo.js builds on the IMS/AS model by providing a secure multi-tenant execution environment for network-based services

• The Tropo.js Provisioning Server maintains a list of apps for each subscriber. Each app contains a set of permissions, allowing the subscriber to control access to their calls and sensitive information.

• Apps are provisioned into and execute in an elastic environment powered by the Cloud Foundry suite of PaaS technologies.

• Only a single IFC entry is required per subscriber as the Tropo.js AS distributes events to all interested applications.

• New services are deployed and provisioned in real-time without adding servers or making any changes to the core network!

Detailed Flow‣ Alice is a sales representative for a local car dealership. She is calling Bob to let

him know that his car is ready for pickup. Prior to making this call, Alice signed up for a cool new service from her mobile carrier that automatically logs her work calls to Salesforce.com

‣ Alice’s mobile network routes her outgoing call to the CSCF, which in turn performs and standard HSS lookup to find Alice’s dialing preferences, roaming status and detailed profile information.

‣ The CSCF finds an IFC entry in Alice’s profile instructing it to route any incoming (INVITE/ORIG) or outgoing (INVITE/TERM) calls through Tropo.js. The CSCF proxies Alice’s outgoing call to the Tropo.js AS via the ISC protocol.

‣ Tropo.js AS uses the P-Served-User header to lookup Alice’s list of applications in the Provisioning Server. At this time, Alice has two two apps provisioned.

‣ Tropo.js AS dispatches an ‘outgoing call’ event to both apps via a secure call+media control protocol called Rayo.

‣ In this example, the SFDC app (orange in color) makes a request to the Web to log a call record in Alice’s CRM.

‣ Using the Route header provided in step 3, the Tropo.js AS sends the call back to the CSCF allowing normal call processing to continue as normal.
