I'd like to interface my UC520 to an overhead paging system (Speco multizone 70v Amplifier)
According to the document below, FXO/FXS isn't an option, only E/M ports
I tried a VIC-2E/M but it doesn't register even after a cold boot.
Has anyone made a VIC2- or VIC3 version work in UC5xx ?
Thanks, ~BAS

"Note: Make sure you understand that this configuration only works for Analog E&M Ports. Do not try to use this configuration with Analog FXS/FXO Ports to interface to an overhead paging system. If you do, your system can be seriously damaged."
