DTMF Transport Using SIP INFO
You can use the SIP INFO method to collect and transport DTMFs. The collection process is regarded as
being an unsolicited one-character timer-less digit collection.
When the feature is enabled:
The Mediatrix 4104 sends a separate SIP INFO method every time a digit is entered during the
call.
The Mediatrix 4104 plays each DTMF sent in a separate message upon receiving a valid SIP
INFO message.
To enable the DTMF transport using the SIP INFO feature:
1.
In the
voiceIfMIB
, set the DTMF transport type in the
voiceIfDtmfTransport
variable
(
voiceIfDtmfTransportTable
group) according to the transport type you want to use.
There are three methods to transport DTMF events:
•
in-band
•
out-of-band using RTP (RFC 2833)
•
out-of-band using SIP INFO
If you set the
voiceIfDtmfTransport
variable to
signalingProtocolDependent
, the remote party
must select one of the two transport types. Transporting DTMF by using RTP has priority over the
SIP INFO method.
DTMF Payload Type
When selecting the
outOfBandUsingRtp
“DTMF Transport Type” on page 235
for
more details), you can determine the actual RTP dynamic payload type used for the “telephone-event” in an
initial offer. The payload types available are as per RFC 1890.
To define the DTMF payload type:
1.
In the
voiceIfMIB
, set the DTMF transport type in the
voiceIfDtmfTransport
variable
(
voiceIfDtmfTransportTable
group) to
outOfBandUsingRtp
.
2.
Set the payload type in the
voiceIfDtmfPayloadType
variable.
Available values range from 96 to 127.
