Running a pair of 8700s on 3.1.2 with a remote G350. I have 3 POTS lines plugged into the Trunk port and the 2 analog line ports. I wanted to create trunk group using the 2 POTS in the analog ports for in and out bound calls. I can't get inbound, outbound, or 2-way working when trunk group is set up as CO or DID. Is it possible to make the 2 analog lines a 2-way trunk group?
