Recommendations
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 6.1
system.
