Patent ID: 7821957

Claim:
A first telecommunications endpoint comprising: a transmitter interface for transmitting, to a second telecommunications endpoint, a first packet stream that conveys a first media waveform a(t); a receiver interface for receiving, from the second telecommunications endpoint, a second packet stream of data that represent a second media waveform a′(t); and a processor for comparing a′(t) with a(t) according to a predetermined characteristic and for adjusting, based on the comparison, the value of a first quality indication, wherein the value of the first quality indication indicates at least one of: I) an acceptable quality based on the comparison of a′(t) with a(t) according to the predetermined characteristic, and II) an unacceptable quality based on the comparison of a′(t) with a(t) according to the predetermined characteristic; wherein a(t) is of a user's voice and a′(t) is a reproduction of the user's voice; and wherein the number of bits transmitted per unit time in the first packet stream of data is affected by the adjusted value of the first quality indication.
