How to use a Cisco 1760V-SRST as a remote office voice gateway 1

[honest1]

I need help to set up a Cisco 1760V-SRST router as a remote office voice gateway. The 1760V will have 4 FXO ports (for local PSTN access). I want to have calls to the remote site office users be answered by the 1760V, sent accross a P-T-P DS-1 to a BCM at the main site, and then have the call routed back accross the P-T-P DS-1 to the user's Nortel IP phone. The BCM at the main site will have it's own local PSTN access.

You'll need a similar router/fxs setup at the BCM site to break the in bound CO lines down to analog lines. Once those analog lines are terminated into the BCM on a CO trunk module, it's just a matter of assigning the lines to ring on the i200x phones.
You'll want to make sure that you configure LLQ or some other QOS mechanism on the WAN link to ensure that your IP phones work well at all times on the backhaul.
SIP trunks may be an option, but I'm not sure if the BCM will support SIP trunks from a non-Nortel gateway.
Good luck.
