T.38 Faxing
To make T.38 faxing, enable T.38 support on the Web. After that, connect a fax machine to a FXS port of the DSL router. Now you
can use it as a normal phone, and it is able to send or receive fax to or from other fax machines on the VoIP network.
In the initial setup, faxing behaves like a normal call. After the DSL router detects the fax tone, it switch to T.38 mode, and use it as
the transmit approach.
Check with your VoIP Provider if your service supports T.38 Faxing.
Pass-Through Faxing
If T.38 support is disabled, faxing uses normal voice codec as its coding approach. Therefore, this mode is more like normal phone
calls.
