David Brillert commented on ASTERISK-20963:
-------------------------------------------

I had a few systems in the field where IAX2 was broken.  Funny but the timer problems also affected DTMF transfers... causing hangups instead of transfers.
The typical cause was a bad dahdi install but after fixing dahdi the timing started working again and IAX2 also started working again.

The command 'timertest' was kind enough to tell me the timer was broken in one case.  But the root cause being a timing issue wasn't obvious at all.  Happy its working again though :)
