Jean-Francois Lemieux commented on ASTERISK-21762:
--------------------------------------------------

Hi everyone; just to give you my cookbook to solve (or bypass ?) the issue

I change in my trunks configuration:

requirecalltoken=yes
 and I added:
transfer=no


I suspect there is a bug in calltoken negociation, even if we put requirecalltoken=no, it will try to negociate call token if the third party support it. I suspect that the trouble start when Asterisk try to transfer a IAX channel, so that's the reason i put transfer=no

Many weeks without the trouble, Before theses changes, I got a crash each week. Maybe a deadlock issue, but I didn't found evidence.
