Voice and data exchange over a packet based network with AGC

One or more circuits for adjusting gain applied to a signal, the one or more circuits comprising:

• at least one processor enabled to receive the signal, the at least one processor operable to, at least:
• apply gain to the signal to produce a signal with gain;
• estimate a power level of the signal with gain;
• and
• selectively output one of the signal and the signal with gain using the estimated power level.

One or more circuits for controlling gain applied to a signal, the one or more circuits comprising:

• at least one interface for receiving the signal;
• and
• at least one processor communicatively coupled to the at least one interface, the at least one processor operable to, at least:
• apply gain to the signal to produce a signal with gain;
• estimate a characteristic of the signal with gain;
• and
• selectively output one of the signal and the signal with gain depending on the estimated characteristic, wherein the selection is based on a threshold.
