Valid Range and Description
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.
AMRFECRedundancyDept
h
Defines the AMR / WB-AMR Redundancy depth according to RFC
3267.
The valid range is 0 to 3. The default is 0.
AMRCoderHeaderFormat
Determines the format of the AMR header.
 [0] (default) = Non standard multiple frames packing in a single RTP
frame. Each frame has a CMR & TOC header.
 [1] = Reserved.
 [2] = AMR Header according to RFC 3267 Octet Aligned header
format.
 [3] = AMR is passed using the AMR IF2 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 gateway
receives a Setup message from the ISDN with 'TransferCapabilities =
data', it can initiate a call using the coder 'Transparent' (even if the
coder 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 gateway must include the 'Transparent' coder in its coder
list.
IsFaxUsed

page 72.
T38UseRTPPort
Defines that the T.38 packets are sent / received using the same port as
RTP 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.
DefaultReleaseCause
For a description of this parameter, refer to 'General Parameters' on
page 103.
IPAlertTimeout
