I will be doing an IPT conversion that uses a Viking ZPI-4 paging interface. I'll be using an fxs port on the gateway for paging. The Viking manual is cryptic and there really isn't too many dip switches on it. I just wanted to see if someone could provide specifics about the hardstraps/config of the Viking before my cut-over, as I hate surprises and want to eliminate as many "known unknowns" as possible! Certainly, the fxs to the "paging in", but how about the "ring-trip/trunk" and "talk batt" switches? THANKS!
