Hitting an interesting problem and just wondering if anyone else has seen similar symptoms...
Working on Vol1, Lab 4A, Task 4.5. This is the task where you set up a SIP Route Pattern and use SIP URI dialing to dial the X-Lite CME SIP Phone (BR2 Ph 4, DN 3006) from the CIPC SIP Phone (HQ Ph2, DN 5002). When dialing from 5002 to 3006 (using the corporate directory on CIPC, as shown in the lab), the X-Lite rings, but hangs up immediately after the call is answered. The output of debug ccsip mess is attached. Looks like the X-Lite is sending a SIP BYE message with the description of "Illegal Sdp Negotiation". I tried a call in the other direction as well - direct dial from 3006 to 5002. The CIPC rings, but you cannot actually answer the call. The debug in this case shows a "503 Service Unavailable" message, and the display on the X-Lite says "Call failed: Service Unavailable". I've double and triple checked all configs (including allow-connections sip to sip), reloaded all routers, Googled for similar issues, and am now officially stumped. :) Debugs attached. Any ideas? cheers, steve
