Command History
Usage Guidelines The moh command configures .au and .wav format music files. Music on hold only works for G.711 calls
and on-net Voice over IP (VoIP) 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 the IP phones get tone on hold. The MOH files are
downloaded to the router’s Flash memory.
Note The music on hold file can be in .wav or.au file format; however, the file format must contain 8-bit 8KHz
data, for example, Consultative Committee for International Telegraph and Telephone (CCITT) a-law or
u-law data format.
Examples The following example sets the music on hold with the music files:
Router(config)# telephony-service
Router(config-telephony-service)# moh minuet.wav
Router(config-telephony-service)# moh minuet.au
filename The music file name.
