Music on Hold (MoH)
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.
Note
To configure music on hold server via web user interface:
1.
Click on
Account
->
Advanced
.
2.
Select the desired account from the pull-down list of
Account
.
3.
Enter the SIP URI (e.g., sip:[email protected]) in the
Music Server URI
field.
4.
Click
Confirm
to accept the change.
When you have placed a call on hold, the held party can hear the music.
Note
For this feature to function, all involved parties cannot use encrypted RTP (SRTP).
Music on hold server is configurable via web user interface only.
If your server supports the MOH feature, you can also upload the custom music file into it
directly. For more information, contact your service provider.
