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.

I have a second customer who has not experienced any failure in months,
running a very similar system. I checked the differences between the two:
Asterisk version (1.6.2.9 vs 1.6.2.12), and Snom without "self"-BLF. So
last week I ported these differences into first system, which has been
running fine since then.

Moreover, I googled a bit about interoperability issues between Snom 3x0
phones and Asterisk, finding some cases not really similar, but suggesting
that BLF function may cause some trouble to Asterisk 1.6.2.x: see e.g.
