This document mainly describes the detailed steps for interfacing the WTU service board with the main control system 3CX.
Two-way calls between the phone and the gateway can be achieved by following the configuration steps below:
•Outbound: from 3CX SIP extension 300 to the gateway via trunk 10000.
•Inbound: calls from outside lines to the gateway, via SIP trunk 10000 to the 3CX, and then through the 3CX to the 300 SIP extensions.
