Name
Description
DTMF transmission
method
Transmission modes of DTMF signal supported by the gateways include RFC 2833, Audio and
SIP INFO. The factory default value is RFC 2833.
RFC 2833
: separate DTMF signal from sessions and transmit it to the platform through
RTP data package in the format of RFC2833;
Audio
: transmit DTMF signal to the platform with sessions;
SIP INFO
: separate DTMF signal from sessions and transmits it to the platform in the form
of SIP INFO messages.
SIP INFO
: send DTMF signals simultaneously via RFC 2833 and SIP INFO.
RFC 2833 payload
type
Used with "RFC 2833" in the DTMF transmission modes. The default value of 2833 payload
type is 101. The effective range available: 96 ~ 127. This parameter should match the setting of
far-end device (e.g. platform).
DTMF tone duration
This parameter sets the on time (in ms) of DTMF signal sent from FXO port.
The default value is 100 ms. The duration time range is 50 ~ 150 ms.
DTMF interdigit
pause
This parameter sets the off time (ms) of DTMF signal sent from port. The default value is 100
ms. The duration time range is 50 ~ 150 ms.
Min. DTMF
detection duration
Minimum duration time of effective DTMF signal. Its effective range is 32 to 96 ms. The
default value is 48 ms. The greater the value is set, the more stringent the detection.
DTMF detection
duration increment
against talk-off
An actual detection threshold is determined by combining the
Min. DTMF detection duration
and this parameter.
Actual detection threshold =
Min. DTMF detection duration
+
DTMF detection duration
increment against talk-off
.
The valid values are 16, 32, and 48 in million seconds. Increase the value can prevent false
detection of DTMF signal.
