[cisco-voip] Dial-Peer Tandom

[Michael L. Windon]

Team,

            Situation: I have two voice gateway located in to locations. One
is 11.11.12.1 and the other is 11.11.12.251. I 11.11.12.251 has  one T1 into
our local PBX at 2/0:1. 11.11.12.251 also has a T1. When the T1 located at
11.11.12.251 is full I want the call to access the VoIP dial peer to access
the other T1 on the other gateway.

>From my understanding of Dial-Peer they act in a hunt group fashion meaning,
when the first dial-peer responds with:

 

The voice port is busy (engaged)

The voice port is out of service

The internal call setup message is rejected

There is no response to the internal call setup message

The voice-cir of the network path does not allow any more voice calls

 

The next dial-peer is chosen which is my next dial-peer that sends the
digits to the other voice GW, but I only get busy as soon as I drop the T1
or all DS0 or busy, your thoughts

 

 

 

 

 

Sincerely,

 

Michael L. Windon
