If your phone can use DNS SRV records it can do it. Or if the phone supports multiple proxy servers. Sent from my iPhone On Sep 19, 2007, at 7:15 AM, "Lucia Rotger" <lrotger@aircomp.aero> wrote:
Hi,
Does that mean the phones must be configured to try ASterisk first, and if they don't succeed then try to reach a SIP VoIP provider like those in that list?
If I understood you correctly, how do I know if a particular SIP phone can do that? or do I insert a SIP proxy between the phones and Asterisk and when Asterisk becomes unreachable the proxy connects the phones elsewhere? I'm assuming a SIP proxy works like a web proxy?

Gateways are usually the better option because you can configure your phones to use it as a failover for WHEN your Asterisk server deadlocks and crashes. A gateway would also provide better echo cancellation and jitter buffer support then a card based solution.
There is a list of BRI gateways on the voip-info wiki here: http://www.voip-info.org/wiki/index.php?page=VOIP+Gateways
