Select the codecs in order according to preference. The
matching codec will be negotiated between caller and
callee.
Configure either ITU-T or IETF encoding format for
G.726 codec. These are two different format of
encoding/decoding G.726 packets defined by IETF
standard and ITU-T standard.
If T.38 is disabled, fax packets will be sent in pass-
through mode with the selected codec. If T.38 is
enabled, fax packets will be sent following the T.38
protocol.
T.38 only works with fax machines that support G3
protocol. If the fax machine supports Super G3 protocol,
disable T.38 to fax in Pass-Through mode. Fax Rate is
fixed at 14.4 kbps.
Configure the recovery level for V21 handshake data.
