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.
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?
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.
Thanks in advance for any info.
