Item Explanation

Relax DTMF If you are having trouble with DTMF detection, you can

relax the DTMF detection.

Echo Cancel Enable/Disable the Echo Cancel function.

Echo Training Enabling echo training will cause the PBX system to

briefly mute the channel, send an impulse, and use the

impulse response to pre-train the echo canceller so it can

start out with a much closer idea of the actual echo. Value

may be "yes", "no", or a number of milliseconds to delay

before training (default = 400)

Busy Detection Used for detecting far end hang up or a busy signal.

Busy Count If Busy Detection is enabled, it is also possible to specify

how many busy tones to wait for before hanging up. The

default is 4, but better results can be achieved if set to 6

or even 8. Mind that the higher the number, the more time

that will be needed to hang up a channel, but lower the

probability that a false detection may occur.

Call Progress If turned on, call progress attempts to determine answer,

busy, and ringing on phone lines.
