T1-Supported Protocols for Cisco Unified MeetingPlace Systems

End-to-end positive disconnect supervision is essential. Without it, Cisco Unified MeetingPlace cannot
reliably tell when a caller hangs up. Many PBX and central office systems can provide disconnect
signaling; we recommend E&M wink start lines because they provide for a positive answer and
disconnect supervision. In many cases, the person taking the order for the lines will not understand your
request, so you will probably need to escalate the request to someone with a technical background.
