Paging Priority Active
You can enable or disable this feature to decide how the phone handles the incoming
multicast paging calls, when there is already a multicast paging call on the phone. If
enabled, the phone will ignore the incoming multicast paging call with a lower priority,
otherwise, the phone will play the incoming multicast RTP and place the previous
multicast paging call on hold. If disabled, the phone will automatically ignore all
incoming multicast paging calls.

1.
Click on Contacts->Multicast Paging.
2.
Select the desired value from the pull-down list of Paging Barge.
3.

phone listens for incoming RTP multicast in the Listening Address field.

receiving the RTP multicast.

Note
Music on hold (MOH) is the business practice of playing recorded music to fill the
silence that would be heard by the callers who have been placed on hold. To use this
feature, you should specify a SIP URI pointing to a Music on Hold Server account, when
placing a call on hold, the phone will invite this SIP URI to the Music on Hold Server
account. The Music on Hold account automatically answers to the SIP INVITE messages
and immediately plays audio from some source located anywhere (LAN, Internet) to the
held party. Contact your system administrator for the SIP URI.
To configure music on hold server via web user interface:
1.
Click on Account.
2.
Select the desired account from the pull-down list of Account.
3.
Click on Advanced>>.
4.
Enter the SIP URI in the Music on Hold Server field.
5.
Click Confirm to accept the change.
The multicast IP addresses range from 224.0.0.0 to 239.255.255.255.
The priorities of listening addresses are predefined: 1 with the highest priority, 10 with the
lowest priority.
Both the multicast paging sender and the receiver will play a warning tone when
pressing the multicast paging key.
