Music on hold (MoH) is the business practice of playing recorded music to fill the silence
that would be heard by the party placed on hold. To use this feature, you should
specify a SIP URI pointing to a Music on Hold Server account. When a call is placed on
hold, the phone will send a SIP INVITE message to the Music on Hold Server account.
The Music on Hold Server 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.
The priorities of listening addresses are predefined: 1 with the highest priority, 10 with the
lowest.
Both the multicast paging sender and the receiver play a warning tone when
establishing a multicast paging call.
Multicast listening addresses are configurable via web user interface only.
