I have an old Panasonic DBS with 40-ish users here in the office and 3 users who work from home (in different cities, mind you). I would really like to give them extensions off of our PBX here so they can have the same phone number(s) as we have at the main office.

I've dug up two OPX adapters and have them sitting on my desk. I'm wondering... I know I need an OL13C between my OPX and the remote station to make this work... question is.. can this be done between different CO's or even between different states? One of my users is in NY (we're in WA). Can this kind of stuff ride a trunk, or is it pretty much only possible within the same CO?

Thanks,

Chris
