Why don't you use FQDN in phone instead of IP of server and configure DNS Server to failover resolve to next IP while set SIP reg expiry same as DNS TTL.

I've configured a WRT54 with 2 LAN ports and arranged for it to fail over when one of the routes is no longer available. That works just fine at the IP level. However, when the router fails over, the phones lose their registration, presumably because their IP address has changed from Asterisk's point of view. The phones happen to be Polycom 335's, and I'm running Asterisk 1.6.2.9. What is the best way to manage this situation so that the phones don't become unavailable during failover? I'm considering using the Tinc VPN solution to prevent the IP address from chaing, but I'm hoping for a more simple solution. Any ideas? -- Take care and have fun, Mike Diehl. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
