OK ... i know the basics... out on an analog extension to a Multi Tech and out over the internet to the remote site then to a Multi Tech and to a S/L phone... then back in through a Multi Tech and into the system on an analog CO Port.

Will an analog extension off of an 016 ETR card work??

How touch is the whole thing to configure on both ends... an hour or two on site and an hour or two on the remote end?

I didn't sell this system and i am not sure i want to dive into this stuff on a system i don't work on much unless it is pretty simple.

Thanks in advance.
