Parameter Description

DTMF Process AVT	Select yes to process RTP DTMF events. Otherwise, select no. If
	this parameter is set to no, the AVT payload type is not included
	in outbound SDP.
	Defaults to yes.
Silence Supp Enable	To enable silence suppression so that silent audio frames are not
	transmitted, select yes. Otherwise, select no. See ”Factors Affecting
	Voice Quality” section on page 39.
	Defaults to no.
DTMF Tx Method	Select the method to transmit DTMF signals to the far end: InBand,
	audio video transport (AVT), INFO, Auto, InBand+INFO, or AVT+INFO.
	InBand sends DTMF using the audio path. AVT sends DTMF as AVT
	events. INFO uses the SIP INFO method. Auto uses InBand or AVT
	based on the outcome of codec negotiation.
	Defaults to Auto.

Dial Plan Parameters

You can configure a dial plan with three interdigit timers:

•Initial timeout (T)—Handset off hook; no digit pressed yet.

•Long timeout (L)—One or more digits pressed, more digits needed to reach a valid number (as per the dial plan).

•Short timeout (S)—Current dialed number is valid, but more digits would also lead to a valid number.
