Note that you have not provided any of the extension numbers, nor described the expected call behavior of the DID, which makes things harder for us. Looking at the trace, it appears to be a normal call. The number called is 6078829030. It gets mapped into sip:[email protected]. sip:1...@... gets mapped into sip:[email protected]:5060, sip:1...@ev..., and sip:~~vm~...@ev... (with priority 0.1). The call is sent to sip:[email protected]:5060. sip:1...@... has no contacts. The interesting bit is the INVITE to sip:[email protected]:5060. It is sent by TCP at 00:20:53Z, and appears to get an immediate ICMP reject. So it is resent by UDP within the same second. The phone responds 100 and 180 within the same second. The 180 is delivered to the originating UA promptly. But the UA (Linksys/SPA2102-5.2.10) responds 200 at 00:21:07Z, which is 14 seconds after ringing starts. Based on your description, it appears that the UA took about 10 seconds after you answered the phone to generate the 200. So it looks like the problem is with the UAs on each end of the call.
