Abstract:
A plurality of audio sources are provided in a Private Branch Exchange (PBX) and monitored to determine if audio is available from any of the sources. Once an audio source with an audio presence has been found, that audio source is connected to the PBX and the PBX uses the audio from that source to provide audio-on-hold to the telephone users at that PBX. The audio coming from that audio source is substantially continuously monitored. When it is determined that this particular audio source is no longer providing audio, this particular audio source is disconnected from the PBX network and another audio source having an audio presence, is connected instead.
