I've got my 1.2.x Asterisk server registering with a SIP provider using their servers DNS entry, not their IP address. My server is behind a NAT. The setup works like a champ for weeks then I get a call reporting inbound calls are failing. When my server isn't registered, inbound callers get a "disconnected" message; very bad. When it happens, I've found that the IP address in the "sip show peers" output isn't correct; it doesn't match what "host sipserver" reports. <BR>
<BR>
Can someone explain to me what Asterisk does in the way of hostname-to-address lookups when it's registering with an external SIP server? What happens when the IP for the name changes?<BR>
<BR>
The provider claims they've changed nothing and a little cron job I setup to look up the DNS entry every 5 minutes didn't catch anything when the fault happened again today. I figure I should see what the expected behavior of Asterisk is in this situation before going back to the carrier.<BR>
<BR>
Thanks in advance for any info.<BR>
