Note
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 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->Advanced.
Multicast RTP is one way only from the sender to the multicast address(es) (receiver). For
outgoing RTP multicasts, all other existing calls on the phone will be placed on hold.
