Music on Hold
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.
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.
