Parameter Description
AMRCoderHeaderFormat
Determines the format of the AMR header.
ƒ
[0]
(default) = Non standard multiple frames packing in a single
RTP frame. Each frame has a CMR & TOC header.
ƒ
[1]
= Reserved.
ƒ
[2]
= AMR Header according to RFC 3267 Octet Aligned
header format.
ƒ
[3]
= AMR is passed using the AMR IF2 format.
TransparentCoderOnDataCall
ƒ
[0]
= Only use coders from the coder list (default).
ƒ
[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 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 device must include the 'Transparent' coder in its
coder list.
IsFaxUsed
For a description of this parameter, refer to ''SIP General
Parameters'' on page
121 .
T38UseRTPPort
Defines the port (with relation to RTP port) for sending and
receiving T.38 packets.
ƒ
[0]
= Use the RTP port +2 to send / receive T.38 packets
(default).
ƒ
[1]
= Use the same port as the RTP port to send / receive T.38
packets.
Notes:
ƒ
For this parameter to take effect, you must reset the device.
ƒ
When the device is configured to use V.152 to negotiate audio
and T.38 coders, the UDP port published in SDP for RTP and
for T38 must be different. Therefore, set the the parameter
T38UseRTPPort to 0.
