SIP User's Manual 4. ini File Configuration
Parameter Description
RTPOnlyMode
For a description of this parameter, refer to ''Advanced
Parameters'' on page 129.
TimeoutBetween100And18x
Defines the timeout (in msec) between receiving a 100 Trying
response and a subsequent 18x response. If a 18x response is
not received before this timer expires, the call is disconnected.
The valid range is 0 to 32,000. The default value is 0 (i.e., no
timeout).
RxDTMFOption
For a description of this parameter, refer to ''DTMF & Dialing
Parameters'' on page 125.
TxDTMFOption
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 125.
For a description on using ini file table parameters, refer to
''Structure of ini File Table Parameters'' on page 233.
DisableAutoDTMFMute
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
