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