Mediant 3000
Parameter Description
EMS: NSE Payload Type
[NSEPayloadType]
Defines the NSE payload type for Cisco Bypass compatible mode.
The valid range is 96-127. The default is 105.
Note: Cisco gateways usually use NSE payload type of 100.
EMS: T38 Use RTP Port
[T38UseRTPPort]
Defines the port (with relation to RTP port) for sending and
receiving T.38 packets.

[0] = (Default) Use the RTP port +2 to send/receive T.38
packets.

[1] = Use the same port as the RTP port to send/receive T.38
packets.
Notes:

For this parameter to take effect, you must reset the device.

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 T38UseRTPPort
parameter to 0.
Web/EMS: T.38 Max Datagram
Size
[T38MaxDatagramSize]
Defines the maximum size of a T.38 datagram that the device can
receive. This value is included in the outgoing SDP when T.38 is
used.
The valid range is 120 to 600. The default is 560.
Web/EMS: T38 Fax Max Buffer
[T38FaxMaxBufferSize]
Defines the maximum size (in bytes) of the device's T.38 buffer.
This value is included in the outgoing SDP when T.38 is used for
fax relay over IP.
The valid range is 500 to 3000. The default is 3000.
Web: Detect Fax on Answer
Tone
EMS: Enables Detection of
FAX on Answer Tone
[DetFaxOnAnswerTone]
Determines when the device initiates a T.38 session for fax
transmission.

[0] Initiate T.38 on Preamble = (Default) The device to which
the called fax is connected initiates a T.38 session on receiving
V.21 Preamble signal from the fax.

[1] Initiate T.38 on CED = The device to which the called fax is
connected initiates a T.38 session on receiving a CED answer
tone from the fax. This option can only be used to relay fax
signals, as the device sends T.38 Re-INVITE on detection of
any fax/modem Answer tone (2100 Hz, amplitude modulated
2100 Hz, or 2100 Hz with phase reversals). The modem signal
fails when using T.38 for fax relay.
Note: This parameters is applicable only if the parameter
IsFaxUsed is set to 1 (T.38 Relay) or 3 (Fax Fallback).
[CEDTransferMode] Determines the fax CED tone transfer mode.

[0] = (Default) The device transfers the CED tone in relay mode
and starts the fax session immediately.

[1] = The device transfers the CED tone in either voice or
bypass mode and starts the fax session on V21 preamble.
Notes:

For this parameter to take effect, a device reset is required.

This parameter is applicable only if the IsFaxUsed parameter is
set to 1 (T.38 Relay).
Web: T38 Fax Session
Immediate Start
[T38FaxSessionImmediateSt
Enables fax transmission of T.38 "no-signal" packets to the
terminating fax machine.

[0] Disable (default)
