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 have been very high. Although much of
the LAN is outside of the control of the PBX, there are several points to consider which 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 for identifying 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 will respond appropriately to a ping or a traceroute message sent from the DEFINITY
MultiVantage™ switch or any other source on your network, although these telephones will not, in
general, initiate a ping or traceroute. Release 1.6 of the 4600 Series IP Telephones introduced "remote
ping" and "remote traceroute" support. The switch can instruct such a 4600 Series IP Telephone to
initiate a ping or a traceroute to a specified IP address. The telephone carries out that instruction and
sends a message to the switch informing it of the results. See your DEFINITY
Administration documentation for more details.
As of Release 1.8, if applicable, 4600 Series IP Telephones test whether the network Ethernet switch port
supports IEEE 802.1D/q tagged frames by ARPing the router with a tagged frame (see
