Version 7.0 937 Mediant 3000
User's Manual 58. Configuration Parameters Reference
Parameter Description
settings of this global parameter is ignored for calls associated with
the IP Profile.
Fax Detect Timeout Since
Connect
[FaxDetectTimeoutSinceConne
ct]
Defines a timeout (in msec) for detecting fax from the Tel side
during an established voice call. The interval starts from when the
voice call is established. If the device detects a fax tone within the
interval, it ends the voice session and sends a T.38 or VBD re-
INVITE message to the IP side and processes the fax. If the interval
expires without any received fax event, the device ignores all
subsequent fax events during the voice session.
The valid value is 0 to 120000. The default is 0. If set to 0, the
device can detect fax during the entire voice call.
SIP T.38 Version
[SIPT38Version]
Determines the T.38 fax relay version.
 [-1] Not Configured = (Default) No T.38
 [0] Version 0
 [3] Version 3 = T.38 Version 3 (V.34 over T.38)
Note:
 Transcoding of T.38 Version 3 is supported only for Gateway
calls. For SBC calls, the device forwards T.38 Version 3
transparently (as is) to the other leg (i.e., no transcoding).
 For a description on V.34 over T.38 fax relay, see V.34 Fax
Support on page 204.
Fax Relay Enhanced
Redundancy Depth
[FaxRelayEnhancedRedundan
cyDepth]
Defines the number of times that control packets are retransmitted
when using the T.38 standard.
The valid range is 0 to 4. The default is 0.
Fax Relay Redundancy Depth
[FaxRelayRedundancyDepth]
Defines the number of times that each fax relay payload is
retransmitted to the network.
 [0] = (Default) No redundancy
 [1] = One packet redundancy
 [2] = Two packet redundancy
Note: The parameter is applicable only to non-V.21 packets.
Fax Relay Max Rate (bps)
[FaxRelayMaxRate]
Defines the maximum rate (in bps) at which fax relay messages are
transmitted (outgoing calls).
 [0] 2400 = 2.4 kbps
 [1] 4800 = 4.8 kbps
 [2] 7200 = 7.2 kbps
 [3] 9600 = 9.6 kbps
 [4] 12000 = 12.0 kbps
 [5] 14400 = 14.4 kbps (maximum for T38 Version 0)
 [6] 16800bps = 16.8 kbps
 [7] 19200bps = 19.2 kbps
 [8] 21600bps = 21.6 kbps
 [9] 24000bps = 24 kbps
 [10] 26400bps = 26.4 kbps
 [11] 28800bps = 28.8 kbps
 [12] 31200bps = 31.2 kbps
