ENDING AND RECEIVING FAX
HT–502 supports fax in two modes: 1) T.38 (Fax over IP) and 2) fax pass through.
T.38 is the preferred method 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.
