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.

If you are looking for a stable version I am running 1.6.1.18 processing
4,000 calls per day with 200 phones. I have had to backport a few patches
from later versions to address some issues I ran into. If you need a
supported release 1.6.2.6 was released at the same time. However they did
change the scheduler for 1.6.2. 

I also have a 1.6.2.9 system with 230 days of uptime that has processed
10,000 calls. This is a small setup with 7 phones.

1.8 works fine with FreePBX. I have two systems systems running 1.8.2.2
with FreePBX 2.7. I'm not a fan of FreePBX 2.8's outbound route dial plan
editor. One box has two phones and the other three phones.

To troubleshoot issues I like to find the version that is stable and the
next version that is unstable. I look through the changelog between these
versions and test reverting various patches until I find the problem patch.
