The following recommendations assist you in determining your trunk requirements and
ordering your trunks from your service provider:
•Make sure you order telephone service early. T1 and PRI service can take up to one
or two months to install.
•If you are reusing Centrex lines, be sure to change your old service and remove call
waiting, call forwarding, and voice mail.
•When provisioning PRI service, be sure to confirm the protocol being used (NI-2,
4ESS, 5ESS, or DMS-100). Make sure that neither NFAS nor the Call-by-Call
feature of the 4ESS is being used, since they are not supported on the ShoreTel 8
