I have a CUCM6BE implementation that uses 2800 routers as Voice Gateways to the PSTN.
The customer has an overhead paging system that consists of a analog 600ohm input to an amplifier which then connects to speakers. The previous PBX had a physical paging port which connected to the amp input.
I need to implement the paging system to the 2800 VGW.
I have found a document that describes the use of E&M for overhead paging. Is it possible to connect the 600ohm analog input directly to pins 4&5 of the E&M port, and then to call this port to access paging?
(Note: There is a PAM10 buffer/filter in front of the amp's input)
Does anyone know if this is possible, using FXS (ideal) or E&M VWICS? Any help would be much appreciated.
Somebody post a solution in this forum several years ago. Use a cheap IP phone and configure auto-answer to headset or speaker. Find the audio cable of headset or speaker. Connect the audio cable to your amplifier. That is it.
Hope this helps.
