Overview
This chapter describes the initial design of the ShoreTel system.
Recommendations
The following recommendations will assist you in designing your new voice communications system.
 Make sure you understand all the unique routing and hunting requirements of your current system.
 Be sure to account for all devices, including conference rooms, lobby phones, fax machines, and
modems.
 Make sure you consider the changes to the call flow and overall system design that may drive the
need for additional trunks.
Network Assessment
As you plan your phone system, ShoreTel recommends that you have a network assessment
performed. A network assessment does the following:
 Ensure necessary protocols and standards are supported
 Confirm that the infrastructure is optimally configured for IP telephony traffic
 Verify that the installed WAN technologies are compatible with IP telephony.
 Measure delay, packet loss and jitter to ensure that they meed acceptable thresholds for toll-
quality voice calls
To complete your system design, the final step is to identify your network connectivity. You should
identify the following for the network connections to each site:
 Bandwidth
 Latency
 Jitter
 Packet Loss
