[Freeswitch-users] [Solved] Callgroup keeps ringing after answer - changed from shared extensions

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.

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.
