Tandem Gateway VoFR/IP

Unanswered Question
Mar 31st, 2008

I've read some threads that indicate Tandem Gateway is not possible between VoIP and VoFR Dial Peers, but I thought I recall utilizing this configuration in the past. Does anyone know of any documentation that indicates whether or not this is possible?

For Example....RouterA--VoIP--RouterB--VoFR--RouterC

I can not find or think of any reason why this would not work. Anyone with a lab that could test this theory?

Also looking for VoIP Tandem Gateway documentation....anyone know of any?

I have this problem too.

That doesn't work because you can't go from a VoFR leg to a VoIP leg directly. You must have pots interfaces in between.

Two E1/T1 PRI ports wit a cross-cable in the same router are ok for that.

Hope this helps, please rate post if it does!
