Call Progress Detection (CPD)

You must enable the answering machine connection for user-terminated scenarios with Call Progress Detection (CPD) capability. This feature is tied to SIP Server and MSML Service.

Enable CPD in your SIP Server

  1. Edit your SIP Server Application, and set TServer/am-detected = connect.
  2. Enable MSML, which is required so SIP Server can communicate with GVP as a Media Server to delegate outbound calls, play treatments, and CPD.
    • TServer/msml-support=true
    • TServer/refer-enable=true
