Intercom Mute
You can mute or un-mute the phone’s microphone for intercom calls automatically. If
Intercom Mute is enabled, the microphone will be muted for intercom calls. If Intercom
Mute is disabled, the microphone will work for intercom calls. Intercom Mute is disabled
by default.
Intercom Tone
You can enable or disable the phone to play a warning tone when receiving an
intercom call. If Intercom Tone is enabled, the phone will play a warning tone before
answering the intercom call. If Intercom Tone is disabled, the phone will automatically
answer the intercom call without warning. Intercom Tone is enabled by default.
Intercom Barge
You can enable or disable the phone to automatically answer an incoming intercom call
while there is already an active call on the phone. If Intercom Barge is enabled, the
phone will automatically answer the intercom call and place the active call on hold. If
Intercom Barge is disabled, the phone will handle an incoming intercom call like a
waiting call. Intercom Barge is disabled by default.
You can use multicast paging to quickly and easily forward out time sensitive
announcements out to people within the multicast group. You can configure a multicast
paging key or a paging list key on the phone, which allows you to send a Real Time
Transport Protocol (RTP) stream to the pre-configured multicast address(es) without
involving SIP signaling. You can configure the phone to receive an RTP stream from
pre-configured multicast listening address(es) without involving SIP signaling. You can
specify up to 10 multicast listening addresses.
