A system and method for detecting and removing tones from an incoming communications channel that may also carry other signals such as, for example, voice is disclosed which includes pre-detecting tones in a communication signal, processing the communication signal to invalidate the tones in response to the tone pre-detection, forwarding the processed communication signal across a network, validating the tone and forwarding tone-on signals across the network in response to the validation.
