echocancelwhenbridged
Generally, it is not necessary (and in fact undesirable) to echo cancel
when the circuit path is entirely TDM. You may, however, reverse this
behavior by enabling the echo cancel during pure TDM bridging.
yes / no
echotraining
In some cases, the echo canceller doesn't train quickly enough and there
is echo at the beginning of the call. Enabling echo training will cause
Asterisk 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 (positive int) to delay
before training.
(default = 400)
faxdetect
Upon fax detection, routes fax to a fax extension.
Both, incoming, outgoing, or no.
group
Logical groups can be assigned to allow outgoing rollover.
Groups range from 0 to 63, and multiple groups can be specified.
hanguponpolarityswitch
In some countries, a polarity reversal is used to signal the disconnect of a
phone line. If this option is enabled, the call will be considered
disconnected on a polarity reversal.
yes / no
