[Asterisk-Dev] Segfault in chan_iax

[Rich Adamson]

And for those that are not sure "how" to change their * system,
iax is like this:
 exten => _6X.,1,Dial(IAX/userid:password at 205.212.173.89/${EXTEN-1})
while iax2 is like this:
 exten => _6X.,1,Dial(IAX2/userid:password at 205.212.173.89/${EXTEN-1})
which can have a couple of different forms (syntax).

And, if you want to get rid of a few unuseless error msgs, add
 noload => chan_iax.so
to the modules.conf
