It's a function of both. When the phone sucessfully registers with an Asterisk system, it stops. The phone therefore only registers with a single Asterisk system, and the same problem still remains. The phone is only registered to one Asterisk system. If that Asterisk system goes down, none of the phones registered to that system can receive calls. However, if by some magic the phone _could_ send another registration, Asterisk would accept it. I've yet to see a phone however, that will send another registration if the first suceeds.

People are used to say, being unable to access a web page for a few minutes. Heck, they might not even notice. However, when someone's phone system goes down, you can bet your bottom dollar that they will notice pretty damn fast, and they expect it to always be working. > > > > If you have your phones register on a 2-min interval, then provided > > Asterisk keeps running for (2min / 0.001%) = 139 days or more, then > > you have "five-nines" (99.999%) availability. > > > > And don't forget that if the phones re-register at 2-min intervals > > randomly spread, the AVERAGE downtime after a failure would > only be one > > minute. > > > > It then becomes a question of whether it is cost-effective > to strive for > > even better than that. > > > > Cheers > > Tony > > -- > > Tony Mountifield > > Work: [EMAIL PROTECTED] - http://www.softins.co.uk > > Play: [EMAIL PROTECTED] - http://tony.mountifield.org > > _______________________________________________ > > --Bandwidth and Colocation provided by Easynews.com -- > > > > Asterisk-Users mailing list > > To UNSUBSCRIBE or update options visit: > > http://lists.digium.com/mailman/listinfo/asterisk-users > _______________________________________________ > --Bandwidth and Colocation provided by Easynews.com -- > > Asterisk-Users mailing list > To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users > _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
