An example of ping usage:
A UNIVERGE SV9100 IP Phone unsuccessfully attempts to connect to the
UNIVERGE SV9100 system as shown in
Figure 1-2 Ping Usage Example .
As seen in Figure 1-2 Ping Usage Example , there are several devices that
could cause a connection problem:

UNIVERGE SV9100 IP Phone (192.168.1.100)

Local Hub

Local Router (192.168.1.1)

Leased Line

Remote Router (192.168.2.1)

Manageable Data Switch

You will see that by pinging from the System IP Phone and PCs, we can work
out where the problem lies by process of elimination. We start by pinging the
nearest device and working outward toward the intended destination.
