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 MoH server account. When a call is placed on hold, the phone
will send a SIP INVITE message to the MoH server account. The MoH 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 MoH server via web user interface:
1. Click on Account->Advanced.
2. Enter the SIP URI (e.g., sip:[email protected]) in the Music Server URI field.
3. Click Confirm to accept the change.
