Music on hold
This feature allows you to put a call on hold and have the other person hear a piece of audio (music, speech, etc.)
you previously recorded.
Application Scenarios:
When one side (A) presses flash or reserve key to put a call on hold, the peer side (B) will receive INVITE
packet with zero IP address in SDP to inform there is no need to send RTP out any more (RFC2543) or change
the attribute field in SDP to recvonly (RFC3261). Phone A generates pre-recorded music from IVR to phone B
directly.
You may configure Music on Hold feature easily on P2602RL-D3A web GUI: VoIP > SIP > SIP setting >
Advanced
In this graph, Device A has enabled Music on Hold function. Thus when A and B are on a call, and if A holds
the call, B will hear the music tone.
