Summary:                    Possible deadlock on 1.6.2.12, 14 and 15
Description: 
After hours to days the system appears to reach a deadlocked state.  SIP
phones lose registration, in-flight calls continue, no new calls can be
established.  Need a "service asterisk restart" to get going again.

Problem is usually first observed when phones lose registration (120
seconds between registrations).

System has never been observed to reach this state overnight or on a
weekend so it appears to only happen when the system is actively handling
calls.

Should also have said...

System comprises some 35 SNOM 320 SIP phones and a few SNOM 360s (with
sidecars).  Lots of BLFs.

2 of the 4 BRI ports are in use, all incoming calls arrive on the B410P. 
Outgoing calls mostly use the B410P (up to two calls) and overflow to a SIP
VSP (infrequent).

A previous implementation with Asterisk 1.4 and mISDN (sorry - don't have
full details to hand - releases were from about 3 to 4 years ago) worked.
