2.8 Sending and Receiving Fax
The VGW-X20FS SERIES gateway supports four fax modes:
T.38 (FoIP)
Pass-through
Modem
Adaptive
T. 38 and Pass-through
2.8.1
T.38 is the preferred fax mode because it is more reliable and works well in most network conditions.
If the service provider supports T.38, please use this method by selecting T.38 as fax mode (default).
If the service provider does not support T.38, pass-through mode may be used. If you have problems
with sending or receiving Fax, toggle the Fax Tone Detection Mode setting.
