[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? -- Take care and have fun, Mike Diehl. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

It'll make them a bit chattier, but it'll make sure Asterisk has the most recent IP address. Shorten it down to as long as you feel the phones can be without service, but also make sure you don't make them too chatty so they're reregistering every second. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Multiple route failover zaps registration
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.

Re: [asterisk-users] Multiple route failover zaps registration
Actually, I've configured the phones to use DNS SRV records to find the Asterisk server, and this works very well. The problem is that when the router fails over, the phones IP address changes and this causes them to be unavailable from Asterisk's point of view.

Re: [asterisk-users] Multiple route failover zaps registration
Hi, I'm only going to rephrase what James said, shorten the registration expiration timer and retry timers. That way phones will retry registrations lets say after 1 min so after 1 min all phones will failover to the secondary SRV record.

The problem is that when the router fails over, the phones IP address changes and this causes them to be unavailable from Asterisk's point of view. And that's why I was suggesting the short registration timer. I'm assuming that the LAN connections/WRT54 is for client phones, not the server. The phone registers, Asterisk sees it as coming from 75.0.0.1 port 5060 (the external IP of the WRT54). And the phone re-registers every 30 seconds, and Asterisk just refreshes the registration. Now, the primary internet connection falls over and the WRT switches to the other connection. If you set the registration timeout to a short interval, the phone sends out a register message and Asterisk sees it as coming from 85.0.0.1, port 5060. Asterisk then updates the registration IP for that peer and it can deliver and receive calls from those phones. The only thing that will happen is that active calls *will* get dropped. There is no way to hide the IP change from that without the VPN tunnel. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
