Hi, I have a really strange problem with a Polycom 430 phone and Asterisk 1.4.20.
Currently If I dial the Polycom from my mobile phone answer the call on the Polycom and then hangup the mobile the call ends fine on the Polycom. But if I call from the Polycom to my mobile and then I hang up the mobile the Polycom thinks the call is still active. However doing a show sip channels shows the the call has ended. Further to that doing a tcpdump shows that Asterisk sends a SIP BYE to the phone but the phone responds with: Status 481 Call Leg/Transaction does not exist. The Polycom is currently associated with 2 sip servers (using 2 lines on the phone) because I am currently in the progress of migrating from one server to another. So the asterisk server is having issues with is on Line 2 and it works perfectly well on Line 1 with a completely different Asterisk server running 1.4.16.2. I haven't tried switching the lines around to see if its just a problem with it being on Line 2. The Polycom is running the latest Bootrom and Sip version. Does anyone have any idea what could be causing this? Cheers, -Joel
