I am sharing this "hair puller" problem in case someone else runs into it. It took 9 months to resolve. I tried to find something different in traces for good/bad calls but nothing. Updated FreeSwitch stable and head many times, no luck. I posted here in April but no responses and found only 1 similar issues searching the web.

Intermittent Problems: Started when all SPA962s changed from shared IDs to unique IDs. 1 - A call is answered and heard but other extensions keep ringing. 2 - A call is answered but there is silence and other extensions keep ringing, pick up one by one, each silence.

Solution: Replaced Cisco/Linksys SPA962s with Yealink T32s (UDP) and iPads (TCP) and have not seen this problem for a 2 months so we're pretty sure it's gone. BTW we really like the T32s (bought based on comments here). Yes I checked and tried many different SPA962 settings, good riddance.

Been at this for 3 weeks now, hope someone can help.... This started after replacing shared extensions with unique users and updating from an early 2011 git.

Ring group via "pointer" works fine as it always has. However, answer via callgroup variable intermittently (30-40%) leaves one or mores phone ringing even though the the call was answered at another extension. The darn thing is that I can't reproduce it myself to get a trace. Any help/suggestions greatly appreciated. Phones are SPA962 (UDP) and Bria on iPad (TCP, same problems) and they all stopped ringing when they shared IDs.
