Allow Collect Calls
Brazil uses a special calling party category for collect calls
(llamadas por cobrar) instead of using the operator (as in
Mexico). The R2 spec in Brazil says a special GB tone
should be used to reject collect calls. If you want to allow
collect calls specify
“yes”, if you want to block collect calls
then say
“no”. Default is to block collect calls.
Category
Caller category to send.
Forced Release
Brazil use a special signal to force the release of the line
(hangup) from the backward perspective. When
forced_release=no, the normal clear back signal will be
sent on hangup, which is OK for all mfcr2 variants I know
of, except for Brazilian variant, where the central will
leave the line up for several seconds (30,60) which
sometimes is not what people really want. When
forced_release=yes, a different signal will be sent to hang
up the call indicating that the line should be released
immediately.
Immediate Accept
This feature allows to skip the use of Group B/II signals
and go directly to the accepted state for incoming calls.
CRC
Enable or disable CRC.
Codec
Set codec:
alaw
ulaw
Echo Cancellation
Enable or disable echo cancellation.
