1. Multicast key sending: When phone A is in standby mode, press the account
1 multicast key, and the pre-configured monitor phone will receive the
multicast RTP stream; if phone A presses the hold key, the receiver will
automatically hang up the multicast RTP session. Press the restore button to
restore the held multicast. Press Hang up to end the multicast RTP session.

the receiver. When the phone is in a call, initiate a multicast RTP session and
the current call is on hold;
2. Multicast will not generate call records.
