Music on Hold (MoH) Configuration
When a call is placed on hold, the phone will send an INVITE message to the specified MoH server account according
to the SIP URI. The MoH server account automatically responds to the INVITE message and immediately plays audio
from some source located anywhere (LAN, Internet) to the held party. For more information, refer to draft RFC draft-
worley-service-example.
The following table lists the parameters you can use to configure music on hold.
