I recently came across a PDF file from the Cisco website that describes the use of analog E&M port/s to connect to an overhead paging system. I'm afraid I forgot the exact URL but I have the file with me.
It has detailed diagrams and stuff but I have not really tried it yet. I really don't know...
I can't setup my 7960 phone to do a conference with 2 external parties. When I call the 2nd party and engage thee conference the phone registers invalid conference participant.
What seems to be the problem?
