Selecting an H.265 Mode
You can select VBR or CBR for the H.265 video codec according to your network bandwidth. This feature is
only applicable to MeetingEye 600/MeetingEye 400/PVT960/PVT940/VC200/VC200-E.
Procedure
1. On your web user interface, go to Account > Codec > Video Codec.
2. Configure and save the following settings:
Parameter Description Configuration Method
H.265 Mode
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.

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.

• Transmission Ways of DTMF
• Setting DTMF Transmission Method for SIP Protocol
• Configuring DTMF for H.323 Protocol
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.
DTMF Keypad Frequencies:
1209 Hz 1336 Hz 1477 Hz 1633 Hz
697 Hz 1 2 3 A
770 Hz 4 5 6 B
852 Hz 7 8 9 C
941 Hz * 0 # D
