Named vs. Sequenced Applications Named applications Named Applications are Selected by the Request Address Examples: Modular Messaging, Voice Portal, Meeting Exchange Sequenced applications A new concept in the Enterprise Communications world A series of applications automatically engaged depending on the user Comes from the Service Provider world but simplified to fit the enterprise Each application in a Sequence Sees all requests Each application can deny, modify, or forward initial SIP requests 8 9. 2011 Avaya Inc. All rights reserved. Tests for Named Applications Does the User Indicate What the Application Is to Do? Does the User Dial A Number to Get this Application? Does the User Expect A Certain Response? Answer of Yes Indicates Strongly a Named Application SM is NOT Needed To Sequence These 9 10. 2011 Avaya Inc. All rights reserved. Tests for Sequenced Applications Does the User Have No Idea the App Is Invoked? Can You Gang Together with Other Apps? Can the Administrator Enable or Disable the Applications without User Knowing? Answer of Yes Indicates Strongly a Sequenced Application SM IS Needed To Sequence These 10 11. 2011 Avaya Inc. All rights reserved. Avaya AuraTM Sequenced Applications Session Manager Direct MediaUser #1 User #2 Billing Service Voice Monitor Call Blocker Enhanced Caller ID Caller ID Converter Personal Assistant Meeting Coordinator CM 11 12. 2011 Avaya Inc. All rights reserved. Examples of Other Sequenced Applications Do-not call and selective call lists White or Black-lists, could depend on time or agent skill Caller-ID manipulation: Outsourcers or partners calling on behalf of their customer Conference bridge selector: Use built in 6-party conferencing first, then automatically switch to conference bridge (internal or hosted) if greater capacity needed Call screener: Could be activated if user is in a meeting or depending on their presence status facebook (or other social network) pop up Selective call recording 12 13. 2011 Avaya Inc. All rights reserved. Benefits of Sequenced Applications Business benefits Increased agility and flexibility Improved customer service Proof points (most provide multiple benefits) Requires no upgrades to the call processing system (Communication Manager / Session Manager) major differentiator from our current model and what our competitors offer Applications can be added / licensed per user or group of users New versions of applications can be added on the fly; migrating part of the users in a pilot Customers / Partners / OEMs can quickly develop new applications; Application development in weeks vs. months Once applications exist customer can deploy them in days vs. weeks or months 13 14. 2011 Avaya Inc.

The DND App (Do Not Call) verifies that the called party is not listed in Do Not Call registry. 4. After Verification, it forwards the call to Session Manager. 5. Session Manager Sequences to the Next Application in the Sequence Session Manager DND App Example: Origination Side Sequencing INVITE SM 14 15. 2011 Avaya Inc. All rights reserved. 1. SM Gets INVITE from Trunk 2. Session Manager Invokes the Term Apps For the Called Party 3. The Call Blocker App Does Not Block Call 4. SM invokes the next application 5. The Call Screening App Checks Called Partys Status 6. Called Party is Busy, Call Screening app Forwards Request to Media Server 7. The Media Server Plays Custom Message Session Manager Call Blocker Media Server Call Screening App Example: Termination Applications SM 15 16. 2011 Avaya Inc. All rights reserved. Applications Can Be Identified as Mandatory or Not An Unresponsive Mandatory Application Will Fail the Call A Timeout will Fail the Call Timer is Settable - Timer B Error Codes of 500,503,408 will Fail the Call If SIP Monitoring has Found the Application Unresponsive, All Calls will Fail CM Should Be a Mandatory Application Other Applications May or May Not Be Mandatory Call Blocker Is Probably Not Mandatory Call Recording May be Mandatory for Finance Transactions Mandatory Applications 16 17. 2011 Avaya Inc.

Enterprise Application recording is down. 6. As recording is NOT Marked Mandatory, so recording is skipped 7. CM is Sequenced 8. Outgoing Call is Sent Session Manager CM DND App record App Example: Non-Mandatory Application Is Down Timeout SM INVITE 17 18. 2011 Avaya Inc. All rights reserved. Geographic Redundancy ASM instances in an enterprise can be geographically distributed separated by WANs, etc. All the ASM instances in an enterprise function as an organic whole to continue providing service to all users should any one ASM instance fail. Each ASM in an enterprise operates in active mode can and does handle INVITE, REGISTER, SUBSCRIBE and other SIP messages Each user in the enterprise is assigned two ASM instances to support that user (proxy, registrar, application sequencer, event-handler for that user!) 18 19. 2011 Avaya Inc.

Session Manager Location Large Enterprises can have Geo Specific Session Managers These can all be controlled through a Common or Duplicated Active/ Active OR Active/ Standby System Managers 19 20. 2011 Avaya Inc.
