DESCRIPTION
Select which standard the MAX208M2W Series uses to handle faxes. The peer
devices must also use standard.
NONE - Disable the fax function.
G.711A Pass Through - Select this option to send and receive fax messages
over the network or Internet using VoIP (G.711a). By encoding fax data as
audio data, faxes may be susceptible to packet loss and other errors.
However, as this standard is considerably older than T.38, it is more
compatible with older orobsolete systems.
G.711U Pass Through - Select this option to send and receive fax messages
over the network or Internet using VoIP (G.711u). By encoding fax data as
audio data, faxes may be susceptible to packet loss and other errors.
However, as this standard is considerably older than T.38, it is more
compatible with older orobsolete systems.
T.38 FAX Relay - Select this if the MAX208M2W Series should send fax
messages as UDP or TCP/IP packets through IP networks. This provides
better quality, but it may have interoperability problems.
