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? Regards, Lucia On Wed, 19 Sep 2007 04:25:41 +0200, Jason Garland <jgarland@gmail.com> wrote:
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
