Overview
The FortiVoice primary rate interface (PRI) gateway works in conjunction with your FortiVoice phone system, an IP private branch exchange (IP PBX), to expand resources and support additional phone lines.
With a PRI gateway, you connect your legacy telephony infrastructure composed of PRI (T1 or E1) digital lines to a FortiVoice phone system.
This document describes how to deploy a FortiVoice PRI gateway.
