[asterisk-users] Multiple route failover zaps registration

[Faisal Hanif]

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.

Subject: [asterisk-users] Multiple route failover zaps registration

Hi all,

I've got a customer who is bringing up a second Internet connection for
fail- over.  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?
