Abstract
A method and apparatus for selectively eliminating nuisance signals during communications connections as during conference calling in which the signals are eliminated when a call path is placed on hold by monitoring signals in a reverse traffic channel from a holding party. If the reverse traffic channel contains a predetermined signal, a music on hold circuit is disabled. When the call is first placed on hold, a check for the predetermined signal is made. If the predetermined signal is not detected during a defined period of time, the music on hold circuit is engaged; otherwise the circuit remains disabled. The predetermined signal may be noise signals, speech signals or a sequence of touch tones or speech representing a command to disable the music on hold circuit. Optionally, a disabled music on hold circuit may be enabled by placing a second command signal, such as speech or touch tones, into the reverse traffic channel.
