VoiceFinder AP200 VoIP Residential Gateway (RGW) User's Guide Version 1.1

5.5.2. Configuring T.38 FAX Relay for VoIP H.323

To configure T.38 Fax Relay for VoIP H.323 for all the connections of a gateway,
which is required, use the following commands in the global configuration
mode:
Step
1 Router(config)#voice service VoIP
2 Router(config-vservice-VoIP)#fax
protocol {t38 [redundancy
3 Router(config-vservice-VoIP)#fax
rate {2400/ 4800 / 7200
/12000 / 14400 / disable }
4 Router(config-vservice-VoIP)#exit
If redundancy is set as 1 or higher, not 0, in the above setting, contents of T.38
packet will be duplicated as many times as the redundancy number and
transmitted.
In this case, higher bandwidth will be required. Therefore, set redundancy as 1
or higher only when there is UDP packet loss in the network. In other cases, set
redundancy as 0.
Set the maximum speed for the fax rate. However, the fax rate is decided by
the transmission cable quality and the transmission speeds of the VoIP gateway
and two fax machines on both sides. If the fax rate is set disabled, T.38 session
will not be opened.
