Voice Gateway

[pcromwell]

I need advice on a design. If you have a remote site on a centralised model, and the Wan link is on a seperate router to the Voice gateway. Would you just configure 1 gateway in UCCM(6.1) and point the relevant digits to the voice

gateway and then create a dial peer to point to the relevant outbound wan router?

This would mean the traffic flow would go from phone, to ccm, to vgwy, then back through same vgwy intface and out through wan router. Is there any issue with doing it like this. I am thinking that you would need to go through the Vgwy in case any transcoding is required.

I guess ideally you would want to have the pstn and wan connection on the same router. but in this case it is not possible.

[A] First part, correct, CUCM it is just aware of IPs.

Please read:

We have tons of docs in our site in how configuring this.

CUCM is never involved in traffic flow UNLESS is acting as Conference resource, MTP or MOH.

CallManager fundamentals and Voice Gateways and Gatekeeper are good books you can check.
