Definitions
In this manual and in the 3CX Phone System Management Console a number of terms
are used:
Port – a port is a physical port on a gateway or VoIP card. In the case of an analog line,
one port equals one PSTN line. In the case of BRI ISDN, one port is 2 PSTN lines, and in
the case of E1 or T1 ports, each port represents 30 and 23 lines respectively.
Virtual Extension Number – this is an extension number assigned to a port. This virtual
extension number is used by the port, together with the authentication ID and the
authentication password, to register with 3CX Phone System.
Port identification – this is a field used to identify the port. You can enter the PSTN line
number here, or simply a text string such as ‘sales’
Step 1: Create the PSTN gateways in 3CX Phone System
