Media

Media offers for kinds of codec, G.711 u-law, G.711 A-law, G.729, G.726, from greatest to lowest in
priority.
Phone: Select to set the following configurations for Phone_1 or Phone_2. When phone1 is selected,
the following set media codec will be applied to phone_1.
T.38: T.38 relay is a way to permit faxes to be transported across IP networks between existing fax
terminals. Click Enable to allow transmission of fax over IP network between two fax machines. If T.38
is disabled, the analog fax signal is transmitted as the normal audio data. If T.38 relay is enabled, the
fax signal is converted to T.38 signal.
G.711u-Law: It is a basic non-compressed encoder and decoder technique. -LAW uses pulse
code modulation (PCM) encoder and decoder to convert 14-bit linear sample.
G.711A-LAW: It is a basic non-compressed encoder and decoder technique. A-LAW uses
pulse code modulation (PCM) encoder and decoder to convert 13-bit linear sample into 8-bit
value.
G.729: It is used to encoder and decoder voice information into a single packet which reduces
the bandwidth consumption.
G.726: It is an
of 32kbit/s.
