the access code.

5.4 FAX Support

HandyTone 386 supports FAX in two modes: T.38 (Fax over IP) and 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 Fax mode to be T.38 (default). If the

service provider does not support T.38, pass-through mode may be used. To send or receive faxes in

fax pass through mode, users must select all the Preferred Codecs to be PCMU/PCMA (G.711-u/a).
