completion. This information along with the IP addresses of the VoIP endpoints
supporting the call are logged locally and optionally sent to an external syslog server
(see Enable Remote System Logging for instructions on enabling logging to a
remote syslog server). Additionally the 4200 will generate a real-time message for
any MOS values calculated less than 2.5 (considered poor quality) during an active
call.
Voice call quality information is found locally in the System Logging Messages
section of the System Information page and a sample output is provided below.
Accessing Troubleshooting Tools
The 4200 provides convenient test tools to facilitate problem isolation and resolution.
A network operator can use these tools to verify connectivity to/from the 4200 as
well as trace datapaths to endpoints throughout the network.
Verify Registered Voice Devices
The 4200 maintains a list of all registered voice devices called a “clients list” so that
it can properly route voice calls. At startup, voice devices register their IP addresses
with the 4200. The 4200 then registers on behalf of the voice devices by providing
its own WAN IP address to the softswitch or IP
PBX. If a user or network operator
reconfigures the IP address of the voice device
it will re-register the new address with the
4200. In this instance voice calls may be
routed improperly because the 4200 clients list
contains out of date information. To update
the clients list simply highlight and delete the
stale entry using the following steps:
A. Select System.
B. Select System Overview.
C. Select Clients List.
D. Proceed to the appropriate signaling
section, highlight the duplicate entry or
entries and press the delete key on the keyboard
