Network Call Routing
This chapter provides an overview of call routing, and digit-manipulation capabilities
of the ShoreTel 6.1 system. The information in this chapter is particularly useful for
administrators of larger, multisite installations.
Overview
When a phone number is dialed in a ShoreTel 6.1 system, the system performs three
distinct operations on telephone numbers:
Digit collection. Voice switches collect the digits in a telephone number.
Network call routing. After collecting the digits, the switch checks the number against
a user’s call permissions, adds trunks to the route list, and makes a final route decision
for the call.
Digit manipulation. The switches manipulate the dialed numbers before outpulsing
them to the service provider.
In this chapter you will learn how to plan your network call routing.
