pick up the target extension’s incoming call by tapping the intercom key. You can configure the
directed call pickup code when configuring an intercom key. For more information, refer to
Configuring an Intercom Key on page 205.

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 a
multicast paging key or 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.
The following describes 31 paging channels:
0: You can broadcast audio to channel 0. Note that the Yealink IP phones running old
firmware version (old paging mechanism) can be regarded as listening to channel 0. It is
the default channel.
1 to 25: You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Polycom IP phones which have 25 channels you
can listen to.
26 to 30: You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Yealink IP phones running new firmware version
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 tap the
intercom key.
