I'm setting up a tie line between a 2921 voice gateway, connected to Call Manager 7 via MGCP, and an Avaya voice gateway. The concept of what I want to do seems simple but for some reason I cannot wrap my head around how to accomplish this.
I want to send all calls coming in on the tie line port 0/0/1 from the Avaya system directly out the PSTN PRI port 0/0/0, no questions asked. My assumption is that the Avaya system will validate that the caller has the correct calling privledges and that the number is formatted correctly before the call is passed onto the Cisco VG.
Conversley I want to send most calls coming in on the PSTN PRI port 0/0/0 out the tie line port 0/0/1 to the Avaya system. Before the call heads out the tie line port I want to append a 6 at the beginning of the incoming number since we're being passed 4 digits but our internal extensions are 5 digits.
There are a few inbound numbers that will be coming in on port 0/0/0 that I want to pull out and send to an AA in Unity, I'm assuming I'd want to append the 6 at the beginning of these calls also to keep our extensions consistent at 5 digits throughout both systems.
I also plan on allowing 5 digit dialing from our Cisco VoIP phones to the Avaya phones, but that part should be a piece of cake.
If someone would be able to give me a nudge in the right direction on what the best way to accomplish this is I would very much appreciate it.
Thanks in advance.
