Description:We have a remote office that's having problems with their Polycom.  
Sometime after they start a conference, the audio will halt and the  
Polycom will become unresponsive.  The only recourse is to kill the  
Polycom meetme.  Symptoms include a flood of RTP packets from the  
Asterisk server to the Polycom, a loss of audio for all participants,  
and the Polycom console becomes frozen.  It appears to be isolated to  
this particular device;  we routinely have conference bridges with  
other offices and Polycoms without issue.

We are using Asterisk 1.4.10.  Here is the output from the channels and "meetme kick".

Comments:By: Jason Parker (jparker) 2008-05-14 12:06:47

I believe that this has already been fixed.

Please always test the latest version of Asterisk before reporting bugs.

If after upgrading to the latest version, you can reproduce this issue, feel free to reopen.

Sorry for re-opening, but I see no other way to ask questions or add comments to this ticket.

Do you have any idea which version might have fixed this?  I'd like to narrow down the problem and see what was fixed.

Please feel free to close this ticket again.

Thanks,
Jason

You are using a version that was released 9 months ago.  There have been 1129 changes since 1.4.10 - your request is quite unreasonable.
By: Jason Dixon (fuzzyping) 2008-06-18 10:52:13

We have upgraded to the following bits, this problem is still reproducible.

asterisk-1.4.21
asterisk-addons-1.4.7
libpmi-1.4.4
zaptel-1.4.10.1

Here is the meetme information from the most recent lockup:

Could you upload the output of a 'sip set debug on' of this phone sending an INVITE (preferably one where you're causing this problem to occur)?

Suspended due to lack of activity. Please request a bug marshal on #asterisk-bugs on the IRC network irc.freenode.net to reopen the issue should you have the additional information requested. Thanks!
