Voice Activation and Silence Detection
The DSP can detect silence and avoid sending packets to the network when
the phone user is not talking. This minimizes network traffic but a confort
noise must be generated on the remote end to make the remote party
understand that the call is ongoing.
This feature can be disable/enabled.
Digit Collection
The dialed digits are collected until a configurable (DigitTout) between 1
and 255 seconds timeout occurs or the hash “#” key is pressed.
