asterisk users - Jun 2005 - Polycoms Go Silent after a a handful of calls.

Hey all, I thought I'd run this by the list before I attempt to go
through official support channels (just because I never get anywhere).
 I've done 3 small business installations with asterisk and polycom
sound point IP 500s.  The first 2 installs run CVS-Head, the most
recent install is just running stable.  Now I have 28 polycom
soundpoint IP 500's on their system, all using SIP no special codecs
or anything.  After taking a handfull of calls some of the phones will
just stop taking recieving voice.  We were able to reproduce it after
about 5 or 6 test calls the called party (polycom phone) could not
hear the calling part(another polycom) using the same calling phone we
called another phone that had taken 0 calls and it worked fine.  At
first we only noticed this on the receptionists phone, so we swapped
in a Cisco phone we had, and it works like a champ.  Has anyone else
seen this problem before?  More importantly has anyone else found a
solution for this?  The phones are all running 1.3.1.  I supposed I
could update them to the latest, but all of our other installations
work flawlessly on the same firmware.

Thanks,
-Ryan

Yeah, It's a fairly common problem with that firmware, I think someone 
attributed it to a memory leak. It seems to have a lot to do with how many 
times a transfer is performed on the phone, so maybe that's why you've
not
seen it before. Upgrade to at least 1.4.1 and you'll see the problem go
away.
