4.3.8 Discontinuous Communication
This section describes how to troubleshoot the fault where the call is discontinuous.
Fault Location
Use the following guidelines to locate the fault:
Check whether the phone is
working properly
Start
Check whether the QoS
priority of the voice service is
set properly
end
Check whether the quality of
the bearer network meets
voice service requirements
CAUTION
To facilitate fault report, save the results of the following steps.
Procedure
Step 1 Replace the phone and check whether the fault is rectified.
l If the fault is rectified, go to Step 7.
l If the fault persists, go to Step 2.
Step 2 In VoIP mode, run the display qos ip and display qos vlan commands to check whether the
QoS priority of the voice service is set properly.
l If the QoS priority of the voice service is set properly, go to Step 4.
l If the QoS priority of the voice service is not set properly, go to Step 3.
NOTE
l When packet loss occurs due to network congestion, the packets whose QoS priorities are the lowest
are discarded firstly. The QoS priority ranges from 0 to 7 from low to high.
l The voice service has high requirements on network quality. Therefore, users are recommended to set
the priority of the VoIP service on the MA5612 to 6.
