This has worked well for us and we haven't seen any problems - in fact we've gained some stability at times. If this is a problem in PJSIP this would be the first time we've encountered a regression. If people feel that we should instead lock versions then this is certainly something we can discuss. What do others think?

Yeah, we've tried things like that both ways.  If you stay on old
versions of PJSIP, you end up with old bugs that never get fixed
(including security vulnerabilities in the SIP stack).  I think we've
leaned towards keeping it up to date being better (as you get bug
fixes in the SIP stack) than trying to own an old version of the code
that very infrequently gets updated.  We have no interest as a
development team to maintain a long running fork of the PJSIP stack -
we tried playing that game for a long time and it was problematic.

There are positives and negatives to both approaches, but the last few
years we've been taking the "keep it up to date approach" instead.
