TxDTMFOption
DisableAutoDTMFMute
Version 5.2
Table 6-7: SIP Configuration Parameters
Valid Range and Description
Determines a single or several (up to 5) preferred transmit DTMF
negotiation methods.
Format of this ini file parameter table:
[TxDTMFOption]
FORMAT TxDTMFOption_Index = TxDTMFOption_Type;
[\TxDTMFOption]
For example:
[TxDTMFOption]
TxDTMFOption 0 = 1;
[\TxDTMFOption]
Notes:
For a description of ini file parameter tables, refer to 'Structure of ini
File Parameter Tables' on page 295.
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 gateway:
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 Embedded Web Server, refer
to 'DTMF & Dialing Parameters' on page 98.
Enables / disables the automatic mute of DTMF digits when out-of-band
DTMF transmission is used.
[0] = Auto 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.
