When the IP address of your asterisk box changed, did you update the externip value to the new ip address in the asterisk config files. http://www.voip-info.org/tiki-index.php?page=Asterisk+SIP+externip
This has bit me in the past when I forgot to make the needed update Just my 2 cents..

The IP address of the Asterisk box they register to has just changed. The DNS entry they were using has changed to reflect the new IP. For some reason or another, using the old A record doesn't work anymore. If I change the registration server to the IP instead of the DNS name, it works fine, so I know the phone is OK. If I query DNS from whatever upstream provider the phone is on, it correctly returns the new IP. It seems to me that these phones have got to be caching the DNS record. Even doing a file system format on the phone didn't clear it out! The TTL on the record was only 4 hours, so at this point I know that any cached copied _should_ have expired. Has anyone else experienced this? Does anyone have any suggestions as to how I might force the Polycom to update its cached copy of the A record?
