Reliability and Performance

There is a cost/performance trade-off associated with Voice over IP. Greater reliability and
improved performance can be obtained through server redundancy and components with
higher bandwidth capabilities.
The reliability and performance of the traditional PBX systems are very high to date. Much of
the LAN is outside the PBX's control. However, consider the points in the next paragraph to
enhance the reliability and performance of the IP telephone network.
All 4600 Series IP Telephones support the tools "ping" and "traceroute." These are standard
LAN/WAN tools to identify:
whether two points on a network can communicate with each other, and
●
what path a sample communication takes as it traverses the network from one point to the
●
other.
All 4600 Series IP Telephones respond appropriately to a ping or a traceroute message sent
from the DEFINITY
telephones will not, in general, initiate a ping or traceroute. Release 1.6 of the 4600 Series IP
Telephones supporting H.323 introduced "remote ping" and "remote traceroute" support. The
