We changed the IPs on our sip servers last night. A few days before we changed them we made the following change in our TA900s:
voice trunk T01 type sip
sip-server primary 216.x.x.x registrar primary 216.x.x.x
to
voice trunk T01 type sip
sip-server primary sip3.atlga.domain.com
registrar primary sip3.atlga.domain.com
Then we changed the A record from the old IP to the new IP. We run a pretty low TTL on that domain and flushed the DNS servers that the TA900s look to. After several hours about 60% of the TA900s required a reboot to resolve the hostname to the new IP and the other 40% won?t do it no matter how many times your reboot. The only fix is to change everything back to IP based using the new IPs. The oldest firmware we are running is T900G2A-A4-02-00-E.biz upto the most recent.
What does "sh hosts" reveal on the non-functional TA900s? Also, are you using SRV records for SIP in your DNS? We do, and have not seen this issue. It _might_ work with just A records but SRV is more flexible, understood by the TA900, and works for us. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
