I too have not found a way to reliably do fallback under the various situations mentioned. Some are easy, others would be fairly hard if not possible to get Asterisk to be able to detect. Then again, fallback doesn't work well on some very expensive standard PBX's I've supported.
If you haven't already thought about it, make sure to put a section in your dial plan to allow users to force the system to use an alternate provider -- like preface with a 6 uses provider 2 instead of the default. Not elegant, but at least it saves a little bit of the hassle on support. If someone's call doesn't go through, they can force it to the backup and try that. Either both won't work (which will help you diagnose the problem when they page you on Sunday afternoon when you're out with your kids), or if it does work at least they have a way to make calls until you get a chance to login and fix the problem. I have my dialplan setup so that the information on which provider to use is pulled as a variable. Then I have an extension in there that will allow you to flip to another provider with a simple phone call from any extension. If need be, I can tell someone over the phone how to do it so they can flip all of the dialplan information to the backup provider so I don't have to rush over there as quickly if one of them goes down. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
