[asterisk-users] SIP Locking Up?

[Jeremy Betts]

I am running a server with a Digium TE410P, about 40 grandstream gxp-2000's,
10 Polycom 500's, running svn branch 1.2 rev 44144, and FreePBX. The server
only has one PRI at the moment, and at times all 23 channels are full, the
phones are all on the local network with the server. Every day or two all
SIP devices seem to stop responding, calls still come in over the zap
channel are handle appropriately  by the queue app and seem to be attempting
to ring the SIP device, but the device never returns the ringing status. The
call then times out and logs out the dynamic agent as it should. When I try
to dial out using a sip device, it seems to hang after I press send and I
see nothing on the Asterisk CLI. Although if I try to dial out using an IAX
device, all is well. If I do a sip show peers all the sip devices show as
registered and qualify. Can someone help me? Is this a bug? How can I
trouble shoot this further?

The log file is here <http://bos.specialtel.com/dbg.txt>

Thanks,
Jeremy
