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.
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.
