This element takes RTP DTMF packets and produces sound. It also emits a message on the GstBus.

The message is called "dtmf-event" and has the following fields

Name	GType	Possible values	Purpose
	G_TYPE_INT	0-1	Which of the two methods specified in RFC 2833 to use. The value should be 0 for tones and 1 for named events. Tones are specified by their frequencies and events are specied by their number. This element currently only recognizes events. Do not confuse with "method" which specified the output.
number	G_TYPE_INT	0-16	The event number.
volume	G_TYPE_INT	0-36	This field describes the power level of the tone, expressed in dBm0 after dropping the sign. Power levels range from 0 to -63 dBm0. The range of valid DTMF is from 0 to -36 dBm0.
method	G_TYPE_INT	1	This field will always been 1 (ie RTP event) from this element.

  "max-duration"             guint                 : Read / Write

The maxumimum duration (ms) of the outgoing soundpacket. (0 = no limit).

Default value: 0

  "unit-time"                guint                 : Read / Write

The smallest unit (ms) the duration must be a multiple of (0 disables it).

Allowed values: <= 1000
