George Joseph commented on ASTERISK-28941:
------------------------------------------

Hi Alan, We've been chasing issues in that pjproject timer code for some time now.   Teluu (the maintainers of pjproject) released version pjproject 2.10 with some timer fixes but we found issues with that release so we hadn't updated Asterisk with it.  Just yesterday, they gave us a patch to test so we're going to try that today and see if we can get something for you to test maybe tomorrow.

> It looks similar to older issues like ASTERISK-27187, though that issue used external pjsip and we're using bundled.
> I have complete core and BT available, if needed.
