[Asterisk-Users] Fail over to Pri on VoIP connection failure

[Cavanna, Richard]

I am trying to tweak my dial plan and I am running into a problem.
Sometimes my VoIP out bound calls do not complete on overseas calls(busy
or just a hang-up).  Is there a way in the dial plan to automatically
dial out of my PRI when something like this happens.  Either by time
limit by a failure event?

Any point in the right direction would be great

Thanks,
