DTMF – RFC 2833 Events
You can define which events will be relayed via RFC 2833. This could be very useful in a Remote Line
Extension scenario, as described in
“Remote Line Extension” on page 325
.
To define the DTMF enforce default events:
1.
In the
voiceIfMIB
, set the DTMF enforce default events in the
voiceIfDtmfEnforceDefaultEvents
variable.
DTMF Transport over the SIP Protocol
You can select the method used to transport DTMFs out-of-band over the SIP protocol.
This feature is effective only if the
voiceIfDtmfTransport
variable is set to
outOfBandUsingSignalingProtocol
(see
“DTMF Transport Type” on page 235
To select the DTMF transport method over the SIP protocol:
1.
In the
voiceIfMIB
, set the DTMF transport type in the
voiceIfDtmfTransport
variable to
outOfBandUsingSignalingProtocol
.
2.
In the
sipInteropMIB
, set the DTMF transport type in the
sipInteropDtmfTransportMethod
variable
(
sipInteropDtmfTransportBySipProtocol
group).
The following methods are available:

RFC 2833: RTP Payload for DTMF Digits, Telephony Tones
and Telephony Signals
Table 151:
DTMF Enforce Default Events
Parameter
Description
enable
Conformance is enforced and support for RFC 2833 implies the support of basic
telephony-events. When setting the variable
voiceIfDtmfTransport
to
outOfBandUsingRtp
(
“DTMF Transport Type” on page 235
), or the variable
telephonyAttributesHookFlashProcessing
to
outOfBandUsingRtp
), the Mediatrix 4104 will advertise the support for events
0-15; it will assume support for events 0-15 when support for RFC 2833 is received
in an announcement.
disable
This creates a deliberate deviance to RFC 2833 as support of basic events is not
automatic. The variables
voiceIfDtmfTransport
and
telephonyAttributesHookFlashProcessing
then act independently to specify which
events will be relayed via RFC 2833. If Hook Flash relay is enabled by itself, support
of event 16 alone will be advertised; if both Hook Flash and DTMF relay are
activated, events 0-16 are supported.
