ini File Parameter Description
EnableSilenceSuppInSDP
Determines the device's behavior upon receipt of SIP Re-INVITE
messages that include the silencesupp:off attribute.
 [0] = Disregard the silecesupp attribute (default).
 [1] = Handle incoming Re-INVITE messages that include the
silencesupp:off attribute in the SDP as a request to switch to the
Voice-Band-Data (VBD) mode.
EnableRport
Enables / disables the usage of the 'rport' parameter in the Via header.
 [0] = Enabled.
 [1] = Disabled (default).
The device adds an 'rport' parameter to the Via header of each outgoing
SIP message. The first Proxy that receives this message sets the 'rport'
value of the response to the actual port from which the request was
received. This method is used, for example, to enable the device to
identify its port mapping outside a NAT.
If the Via doesn't include 'rport' tag, the destination port of the response
is taken from the host part of the Via header.
If the Via includes 'rport' tag without a port value, the destination port of
the response is the source port of the incoming request.
If the Via includes 'rport' tag with a port value (rport=1001), the
destination port of the response is the port indicated in the 'rport' tag.
VBRCoderHeaderFormat
Defines the format of the RTP header for VBR coders.
 [0] = Payload only (no header, no TOC, no m-factor) -- similar to
RFC 3558 Header Free format (default).
 [1] = Supports RFC 2658 - 1 byte for interleaving header (always 0),
TOC, no m-factor.
 [2] = Payload including TOC only, allow m-factor.
 [3] = RFC 3558 Interleave/Bundled format.
TransparentCoderOnData
Call
 [0] = Only use coders from the coder list (default).
 [1] = Use transparent coder for data calls (according to RFC 4040).
The 'Transparent' coder can be used on data calls. When the device
receives a Setup message from the ISDN with 'TransferCapabilities =
data', it can initiate a call using the coder 'Transparent' (even if the code
r
is not included in the coder list).
The initiated INVITE includes the following SDP attribute:
a=rtpmap:97 CLEARMODE/8000
The default Payload Type is set according to the CoderName table. If
the Transparent coder is not set in the Coders table, the default value is
set to 56. The Payload Type is negotiated with the remote side, i.e., the
selected Payload Type is according to the remote side selection.
The receiving device must include the 'Transparent' coder in its coder
list.
IsFaxUsed
For a description of this parameter, refer to ''SIP General Parameters''
on page 134.
T38UseRTPPort
Defines the port (with relation to RTP port) for sending and receiving
T.38 packets.
 [0] = Use the RTP port +2 to send / receive T.38 packets (default).
 [1] = Use the same port as the RTP port to send / receive T.38
packets.
