Parameter Value
t38_fax_transcoding_MMR
Specifies whether the API can convert to and from MMR fax compression to
reduce the bandwidth of the transport mechanism when using a reliable
transport (for example, TCP). Set this parameter to:
FALSE Indicates that the API does not support the capability.
TRUE Indicates that the API can convert MMR compression.
Value type: Boolean
Default value: FALSE
Note
This parameter does not affect the normal T.30-level capability to use
MMR if the two endpoints select MMR as a line compression format.
t38_fax_udp_ec
Specifies a value that identifies the error correction method of the T.38 fax
transport. Set this parameter to:
t38UDPFEC The transport uses the T.38 user datagram protocol
(UDP) forward error correction (FEC) method (not supported).
t38UDPRedundancy The transport uses the T.38 UDP redundancy
error correction method.
Value type: character string
Default value: t38UDPRedundancy
t38_max_bit_rate
Specifies a value that defines the maximum bit rate for fax packetization
onto the network. Set this parameter to:
2400 Represents the maximum bit rate that can be negotiated for fax
packetization.
4800 Represents the maximum bit rate that can be negotiated for fax
packetization.
7200 Represents the maximum bit rate that can be negotiated for fax
packetization.
9600 Represents the maximum bit rate that can be negotiated for fax
packetization.
12000 Represents the maximum bit rate that can be negotiated for
fax packetization.
14400 Represents the maximum bit rate that can be negotiated for
fax packetization.
Unit: bits per second
Range: 2400, 4800, 7200, 9600, 12000, 14400
Value type:decimal
Default value: 14400
t38_t30_fastnotify
Specifies whether the transport signals the beginning of T.30 by means of a
zero-length data field or uses a T.30 indicator value. Set this to parameter
to:
FALSE: Indicates that the T.38 fax transport uses a zero-length data field to
signal the beginning of T.30.
TRUE: Indicates that the transport uses a T30_INDICATORvalue to signal
