Step Command Remarks
8. Configure the number
sending mode.
send-number
{ digit-number | all |
truncate }
Optional.
By default, the truncate mode is used, that is,
numbers matching the wildcard dot (.) at the
end will be sent.
For more information about the above commands, see "Configuring dial plans."
Configuring the jitter buffer
Jitter, packet loss, and packet disorder occurs during the transmission of voice packets over IP networks.
By using a series of adaptive algorithms, the jitter buffer stores the received IP packets for a period of time
and sends the packets in evenly spaced intervals. The jitter buffer reduces packet delay and jitter, and
improves the communication quality.
To configure the jitter buffer:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter voice view.
voice-setup N/A
3. Enter voice dial program view.
dial-program N/A
4. Create a POTS voice entity
and enter POTS voice entity
view.
entity entity-number pots N/A
5. Set the operating mode of the
jitter buffer to adaptive.
jitter-buffer mode adaptive
Optional.
By default, the adaptive mode is
disabled and the jitter buffer does
not buffer any voice packet.
6. Set the operating parameters
for the jitter buffer that
operates in the adaptive
mode.
jitter-buffer delay { initial
milliseconds | maximum
milliseconds }
Optional.
By default, the initial buffering time
is 30 milliseconds and the
maximum buffering time is 160
milliseconds.
