Diagnosing and isolating voice-quality problems

To isolate voice-quality problems, access network diagnostic utilities on
an IP Phone. You can run directly the utilities from the IP Phone itself or
remotely through a CLI. Diagnostic utilities include the following:
•
Ping and Traceroute
Run the Ping or Traceroute command from a specific endpoint with any
destination, typically another endpoint or Signaling Server.
•
IP Networking statistics
View information on the packets sent, packets received, broadcast
packets received, multicast packets received, incoming packets
discarded, and outgoing packets discarded.
•
Ethernet statistics
For an IP Phone on a particular endpoint, view Ethernet statistics,
such as number of collisions, VLAN ID, speed, and duplex. The exact
statistics depend on what is available from the IP Phone for the specific
endpoint.
•
UNISTIM/RUDP statistics
View RUDP statistics for IP Phones, such as number of messages sent
or received, retries, resets, and uptime.
•
UNIStim Security with DTLS
