The blip at the beginning is expected; the DTMF detector won't trigger until it has seen a long enough continuous tone to recognize it, and then it will begin muting the audio. The only way around this would be to artificially delay the audio stream by 20-40ms to accommodate the muting, but most people would not enjoy the additional latency this would create. -- Kevin P.
