Configuring Music on Hold
The music on hold (MOH) feature supports .au and .wav format files. Music on hold works only for
G.711 on-net Voice over IP (VoIP) calls and Public Switched Telephone Network (PSTN) calls. For all
other calls, tone on hold works where the user hears a periodic beep. The internal calls between
Cisco IP phones do not get music on hold, instead they get tone on hold.
