I have done some digging into this crash, at I do think it is related to
the recent update, but not convinced it actually fixed the problem and not
just avoid it.

                peer->historicms = 0;


On my box, I do not have a dnsmgr.conf file, and therefore, dnsmgr is off.
Does iax2_poke_peer get called at the beginning, setup, duration, or end of
an IAX call?

The real question is should iax2_poke_peer really return 0 if there is a
fixed IP address, and no dnsmgr? I would think a fixed IP would function
fine with no dnsmgr.
