5. Now all three parties are in a three-way conference.
T38 Faxing
To make T38 faxing, enable T38 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 T38 mode, and use it as
the transmit approach.
Pass-Through Faxing
If T38 support is disabled, faxing uses normal voice codec as its coding approach. Therefore, this mode is more like normal phone
calls.
