Parameter Description
Packing Factor
[RTPPackingFactor]
N/A. Controlled internally by the device according to the selected
coder.
Basic RTP Packet Interval
[BasicRTPPacketInterval]
N/A. Controlled internally by the device according to the selected
coder.
RTP Directional Control
[RTPDirectionControl]
N/A. Controlled internally by the device according to the selected
coder.
RFC 2833 TX Payload Type
[RFC2833TxPayloadType]
N/A. Use the ini file parameter RFC2833PayloadType instead.
RFC 2833 RX Payload Type
[RFC2833RxPayloadType]
N/A. Use the ini file parameter RFC2833PayloadType instead.
RFC 2198 Payload Type
[RFC2198PayloadType]
RTP redundancy packet payload type, according to RFC 2198.
The range is 96-127. The default is 104.
Note: This parameter is applicable only 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
[EnableStandardSIDPayload
Type]
Determines whether Silence Indicator (SID) packets are sent
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.
Comfort Noise Generation
Negotiation
[ComfortNoiseNegotiation]
Enables negotiation and usage of Comfort Noise (CN).
[0] Disable = Disable (default).
[1] Enable = Enable.
The use of CN is indicated by including a payload type for CN on
the media description line of the SDP. The device can use CN with
a codec whose RTP timestamp clock rate is 8,000 Hz
(G.711/G.726). The static payload type 13 is used. The use of CN
is negotiated between sides. Therefore, if the remote side doesn't
support CN, it is not used.
Note: Silence Suppression must be enabled to generate CN.
Analog Signal Transport Type
[AnalogSignalTransportType
]
Determines the analog signal transport type.
[0] Ignore Analog Signals = Ignore (default)
[1] RFC2833 Analog Signal Relay = Transfer hookflash via RFC
2833
RTP Base UDP Port
[BaseUDPPort]
Lower boundary of UDP port used for RTP, RTCP (RTP port + 1)
and T.38 (RTP port + 2). The upper boundary is the Base UDP
Port + 10 * (number of device's channels).
The range of possible UDP ports is 6,000 to 64,000. The default
base UDP port is 6000.
For example: If the Base UDP Port is set to 6000 (default) then:
1) The first channel uses the following ports RTP 6000, RTCP
6001, and T.38 6002, 2) the second channel uses RTP 6010,
RTCP 6011, and T.38 6012, etc.
Note: If RTP Base UDP Port is not a factor of 10, the following
