Hi all, I would like to have two asterisk servers in a "cluster". From what I understand using a mysql database I can store all of my peer/user information in the db and share this between servers. I can then take my polycom phone and register it to both of the asterisk servers at the same time - so if one were to go offline traffic would be redirected to the second. This works in theory for the end user - but how do I provide redundancy with my upstream providers? I.e. how do I fail over my registration to an upstream sip provider? Thanks in advance, Max -- Max Clark max [at] clarksys.com http://www.clarksys.com
You can simply put then in order in your dial plan:
exten => _1NXXNXXXXXX,1,Dial(SIP/${EXTEN}@carrier1}
exten => _1NXXNXXXXXX,2,Dial(SIP/${EXTEN}@carrier2}
and so on. if carrier1 returns an error, * will dial out using carrier2.

With this setup Asterisk will also dial out using carrier2 even if the call via carrier1 does NOT fail. It will dial out via carrier2 if the number is busy, disconnected, answered then ended, etc. This is BAD BAD BAD. Try looking at std-exten for an example of how to handle stuff when Dial exits.

Try something like this.
Note: I did not write these scripts. I would give credit to who did, but
unfortunately I do not remember where I got it.
