DTMF Tx Strict
Hold Off Time:
FAX Process NSE
Hook Flash Tx
Method
FAX Disable ECAN
Release Unused
Codec
This parameter is in effect only when "DTMF Tx Mode" is
set to "strict," and when"DTMF Tx Method" is set to out-of-
band; i.e. either AVT or SIP-INFO. The value can be set as
low as 40 ms. There is no maximum limit. A larger value
will reduce the chance of talk-off (beeping) during
conversation, at the expense of reduced performance of
DTMF detection, which is needed for interactive voice
response systems (IVR).
Default: 90 ms
To use the fax process NSE feature, select yes. Otherwise,
select no.
The default is yes.
Select the method for signaling hook flash events: None,
AVT, or INFO. None does not signal hook flash events. AVT
uses RFC2833 AVT (event = 16). INFO uses SIP INFO with
the single line signal=hf in the message body. The MIME
type for this message body is taken from the Hook Flash
MIME Type setting.
The default is None.
If enabled, this feature automatically disables the echo
canceller when a fax tone is detected. To use this feature,
select yes. Otherwise, select no.
The default is no.
This feature allows the release of codecs not used after
codec negotiation on the first call, so that other codecs
can be used for the second line. To use this feature, select
yes. Otherwise, select no.
The default is yes.
