Using Intercom
You can use the intercom key in the following ways:
Place a call to the target extension
Pick up an incoming call of the target extension
Note
Placing an Intercom Call to the Target Extension
To place an intercom call when the target phone is idle:
1.
Press the intercom key.
The target extension plays a warning tone and automatically answers the call in the
hands-free (speakerphone) mode by default.
Picking up an Incoming Call of the Target Extension
When the target extension receives an incoming call, the intercom key LED of the target
extension will flash green. If you configure the directed call pickup code in advance, you can pick
up the target extension’s incoming call by pressing the intercom key. You can configure the
directed call pickup code when configuring an intercom key. For more information, refer to
To pick up an incoming call when the monitored phone is ringing:
1.
Press the intercom key.
The incoming call of the target extension is answered on the IP phone.
Note
Multicast Paging
You can use multicast paging to quickly and easily broadcast time sensitive announcements to
users who are listening to a specific multicast group and a specific channel. You can configure
the 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) and channel(s) without involving SIP
signaling. You can configure the phone to receive an RTP stream from pre-configured multicast
listening address(es) and channel(s) without involving SIP signaling. You can specify up to 31
multicast listening addresses and channels.
If the directed call pickup code is not configured, the phone will place a call to the target
extension instead of picking up an incoming call of the target extension when you press the
intercom key.
To use the intercom key to pick up an incoming call, make sure the intercom subscription feature
is enabled. For more information, contact your system administrator.
