ini File Parameter

SIP User's Manual
This ini file table parameter determines a single or several (up to 5)
preferred transmit DTMF negotiation methods.
The format of this parameter is as follows:
[TxDTMFOption]
FORMAT TxDTMFOption_Index = TxDTMFOption_Type;
[\TxDTMFOption]
For example:
[TxDTMFOption]
TxDTMFOption 0 = 1;
[\TxDTMFOption]
Notes:
DTMF negotiation methods are prioritized according to the order of
their appearance.
When out-of-band DTMF transfer is used ([1], [2], or [3]), the
parameter DTMFTransportType is automatically set to 0 (DTMF
digits are erased from the RTP stream).
When RFC 2833 ([4]) is used, the device:
1) Negotiates RFC 2833 Payload Type (PT) using local and remote
SDPs.
2) Sends DTMF packets using RFC 2833 PT according to the PT in
the received SDP.
3) Expects to receive RFC 2833 packets with the same PT as
configured by the parameter RFC2833PayloadType.
4) Uses the same PT for send and receive if the remote party doesn't
include the RFC 2833 DTMF PT in its SDP.
When TxDTMFOption is set to [0], the RFC 2833 PT is set according
to the parameter RFC2833PayloadType for both transmit and
receive.
For defining this parameter using the Web interface, refer to ''DTMF
& Dialing Parameters'' on page 160.
For a description on using ini file table parameters, refer to ''Structure
of ini File Table Parameters'' on page 293.
Enables / disables the automatic muting of DTMF digits when out-of-
band DTMF transmission is used.
[0] = Automatic mute is used (default).
[1] = No automatic mute of in-band DTMF.
When DisableAutoDTMFMute = 1, the DTMF transport type is set
according to the parameter DTMFTransportType and the DTMF digits
aren't muted if out-of-band DTMF mode is selected (TxDTMFOption =1,
2 or 3). This enables the sending of DTMF digits in-band (transparent of
RFC 2833) in addition to out-of-band DTMF messages.
Note: Usually this mode is not recommended.
Determines if and when the device sends a 100 Trying response to an
incoming INVITE request.
[0] = 100 Trying response is sent upon receipt of Proceeding
message from the PSTN.
[1] = 100 Trying response is sent immediately upon receipt of
INVITE request (default).
For a description of this parameter, refer to ''SIP General Parameters''
on page 134.
