Minimum delay for the Dynamic Jitter Buffer.
The valid range is 0 to 150 milliseconds. The default delay is 10
milliseconds.
Note: For more information on the Jitter Buffer, refer to 'Dynamic
Jitter Buffer Operation' on page 350.
Dynamic Jitter Buffer
Optimization Factor
[DJBufOptFactor]

The valid range is 0 to 13. The default factor is 10.
Notes:
 Set to 13 for data (fax and modem) calls.
 For more information on the Jitter Buffer, refer to 'Dynamic
Jitter Buffer Operation' on page 350.
RTP Redundancy Depth
[RTPRedundancyDepth]
 [0] 0 = Disable the generation of redundant packets (default).
 [1] 1 = Enable the generation of RFC 2198 redundancy
packets.
Packing Factor
[RTPPackingFactor]
N/A. Controlled internally by the gateway according to the selected
coder.
Basic RTP Packet Interval
[BasicRTPPacketInterval]

The range is 96-127. The default is 104.
Applicable if RTP Redundancy Depth = 1.
Fax Bypass Payload Type
[FaxBypassPayloadType]
Determines the fax bypass RTP dynamic payload type.
The valid range is 96 to 120. The default value is 102.
Enable RFC 3389 CN Payload
Type
[EnableStandardSIDPayloadTy
pe]
Determines whether Silence Indicator (SID) packets that are sent
and received are according to RFC 3389.
 [0] Disable = G.711 SID packets are sent in a proprietary
method (default).
 [1] Enable = SID (comfort noise) packets are sent with the RTP
SID payload type according to RFC 3389. Applicable to G.711
and G.726 coders.
