The SIP call flows below show an example of implementing the device's AMD feature. This
scenario example allows a third-party Application server to play a recorded voice message
to an answering machine.
1.
Upon detection by the device of the answering machine, the device sends a SIP INFO
message to the Application server:

The device then detects the start of voice (i.e., the greeting message of the answering
machine), and then sends the following to the Application server:
