Try using IP addresses instead of hostnames in sip.conf.  Asterisk's DNS 
support is supposed to be improved in CVS-HEAD, but you should still try it.

However, using an IP address instread of a hostname in your host= line 
could have issues with some ways a provider might do failover and load 
balancing.
