That's interesting, binding it to the internal nics ip... Nate's post has
me resolved to just go in on a Saturday and sit at the console running some
tests. But with this in mind, I might be better armed for success.

I also found someone suggesting not to use the fqdn in the sip peer reg, as
he had the same issues I do.

Lots of love for Asterisk, but I may resolve to learning Freeswitch as I
am thinking the developer has fixed some long outstanding problems with
Asterisk. The ast devs would argue a robust network is required, but
core dumping when a dns query fails? WTF kind of code is that?

Thanks for the good idea!
