It's my (limited) understanding that the IAX2 channel driver in Asterisk
1.2 caches any DNS names it resolves, and doesn't bother looking them
back up later.

Fortunately, that problem has been addressed in later versions of
Asterisk.  If I remember correctly, Asterisk 1.6.0 and later use the DNS
Manager (see dnsmgr.conf) to periodically re-resolve DNS names.
