1 Integrating next generation multimedia services to existing telephones ACOT 2004 Tim Youm Nortel Networks PG 1

2 Introduction In today's voice network, there are still many traditional voice system which are not capable of delivering multimedia services. At the same time, there are constantly new multimedia features are being developed through different platforms/technology hence this session is focusing on how these new type of multimedia services (Video, presence, IM, app sharing, conferencing etc) can be fully integrated into existing telephones ensuring that end user can maintain existing telephone number/address and have additional multimedia capabilities. PG 2

3 Problems: Too many numbers/addresses for communication devices Mobile number Office Number Mobile Voic Office Voic PG 3

4 Converged Desktop Solution: Multimedia Services - Taking existing Telephone Services to a New Level! Telephony Device Multimedia Device Video IM/Presence Collaboration Mobility Extensive Voice Services Reliability Multimedia Capability Flexibility Mobility Complementary services using familiar user interfaces PG 4

5 Benefits of Converged Desktop Solution End users can keep using their existing telephone No fear of lost services (if its not broke, don t fix it!) Less stringent enterprise data network requirements (don t have to make the data network QoS enabled for Converged Desktop) Allows TDM Centrex or key system operators to offer new, multimedia services Allows for existing enterprises to multi-media enable their end users PG 5

6 Converged Desktop Solution Goal MM Call from CDS User 3 1. Call from Blended User 2. Alert Phone and (voiceless) MM Client 3. MM Client screen pop, with 10 sec delay 4. Collab / IM / etc. call-back established to user MM Call to CDS User Call from Regular MM Client User 2. MM App Server determines that terminator is Voiceless Blender sends call to PSTN 4 3. Alert Phone and (voiceless) MM Client 4. MM Client screen pop, with 10 sec delay 5. Collab / IM / etc. call-back established to user PG 6

7 Converged Desktop Solution SIMRING MM App server Receives a CD Call through a Trunk End Office SimRings MCP Number & TDM Line IN / Convergence End Office uses IN Trigger as a stimulus, messages MM App Server (via SG), MM App Server uses Personal Agent Routing for call s multi-media enhancement and directs the End Office to ring TDM Line Class5 Dialog Convergence with Class 5 SS Optimized for Pure Environment No IN-triggers Class5 Class5 SG MM App Server LAN MM App Server LAN MM App Server LAN Converged Desktop Converged Desktop Converged Desktop PG 7

10 2: Converged Desktop Solution: IN DN= , , 5545 Has Simultaneous Ring feature to call to virtual no to MM app server via -T trunk / E1 as well as initiate IN trigger to MM App server via SG CS1R/AIN Class 5 GW MM app server State full session But require SG to convert from CS1R/AIN to = Full MM integration with existing voice system TDM/IP -T IP Phone/TDM phone Public no: Short Dial No: Ext: 5545 Multimedia Client Address=tyoum@nortelnetwroks.com Converged Alias: 55545@nortelnetworks.com Tim Youm Ph: Username: tyoum@nortelnetworks.com PG 10

11 Call Flow: call from CD to CD (IN--Dialog) Originating Converged Phone PAD-A Originating Switch SCP Application Server Terminating Switch Terminating Converged Phone PAD-B 1. Calling PAD-B 2. Trigger (off hook delay) 3. NOTIFY Converged Server;(Event: call log; presence on the phone) OK 5. Trigger (Analyze_Route) 6. Call PAD-B 7. Trigger (Terminating Attempt) 8. INVITE: ConvergedService From: PAD-A TRYING Moved Temporarily (Action: Continue to PAD-B) 11. ACK 12. Authorize Termination 13. Call PAD-B 16. Ringing 19. Answer 15. Ringing 18. Answer 14. Ringing 17. Answer 20. Release 21. Trigger (Termination Notification) 22. NOTIFY PAD-A (Converged Server;(Event: call log; presence is idle) OK 24. Release 25. Trigger (Termination Notification) 26. NOTIFY PAD-B (event: Call Released) OK 28. Release PAD-B PG 11

12 3: Converged Desktop Solution: Message DN= , , 5545 Has Simultaneous Ring feature to start the dialog session to virtual no to MM app server via trunk Class 5 MM app server State full session = Full MM integration with existing voice system TDM/IP IP Phone/TDM phone Public no: Short Dial No: Ext: 5545 Multimedia Client Address=tyoum@nortelnetwroks.com Converged Alias: 55545@nortelnetworks.com Tim Youm Ph: Username: tyoum@nortelnetworks.com PG 12

13 Converged Desktop Common Multimedia Feature Definitions TDM Voice Feature Preservation Presence Personal Agent Call Logging Picture Calling Line ID Instant Messaging File Transfer White Boarding Web Page Push Clip Board Transfer Click To Call Point to Point Video All system telephony features work the same after Converged Desktop is added Reports if you are Online, Inactive, On the Phone, Away to other users Call Manager (screening, routing), Directories, User Settings, Web Client Inbox and Outbox records for all calls - accessible from PC Client A photo of the Calling Party is presented in the Call Control Screen Pop IM between any two users. Multiple simultaneous sessions are supported Send any file on your PC directly to another user Collaborate simultaneously with another user using this drawing/text tool Send a Web Page directly to another user their browser will auto-launch Send the contents of your Clip Board directly to another user Click on Directory Entry, Call Log, Outlook Message to place a call Point to point video - automatically launches and ends with voice call PG 13

14 Converged Desktop Feature Support per implementation Full Partial Not Available Feature / - T SimRing Calls IN(CS1R)/ Messaging Voice Feature Preservation Presence Follow me Find me Call Logging (only manual no auto-presence) (use of Routes can be complex due to SIMRING) (incoming call only) (manual and auto-presence) (less Routing interactions as there is no SIMRING provisioning) (incoming & outgoing calls) Picture Calling Line ID Instant Messaging File Transfer White Boarding Web Page Push Clip Board Transfer Click To Call Video (Video session is sperate to Voice) Call Control (Call Hold, Call forward etc) PG 14
