DTMF

DTMF is the signal sent from the system to the network, which is generated when pressing the keypad
during a call. Each key pressed generates one sinusoidal tone of two frequencies. One is generated from a
high-frequency group and the other from a low-frequency group.

DTMF Keypad
The DTMF keypad is laid out in a 4×4 matrix, with each row representing a low frequency, and each
column representing a high frequency. Pressing a digit key (such as '1') will generate a sinusoidal tone for
each of two frequencies (697 and 1209 hertz (Hz)). The switch can decode the frequency group and locate
the corresponding key.

Description
H.265 video codec.
VBR- the output data rate
•
of the H.265 codec varies
per time segment. You
can save nearly half the
bandwidth.
• CBR- the output data
rate of the H.265 codec
is constant. If the latency
issue appears in the
call or video image is
abnormal, it may result
from packet loss, you can
select this value to try to
fix this issue.
Default: VBR.
