Virtual Private Network (Vpn) - Panasonic KX-TDA30 Features Manual

1.29.3 Virtual Private Network (VPN)

Description
Virtual Private Network (VPN) is a service provided by the telephone company. It uses an existing line as if
it were a private line. There is no need to set up a private line or to lease a line from the telephone company.
Making and receiving both public and private calls is possible using the same line.
Public/Private Discrimination:
a)
When making a call: The public/private discrimination number is required before sending the
dialled number to the telephone company. The public/private discrimination number can be dialled
manually, or automatically by ARS programming (→ 1.9.1 Automatic Route Selection (ARS)) and/
or TIE line service programming.
b)
When receiving a call: The telephone company distinguishes the call type. If it is a private call,
the call is received by the TIE line service method. If it is a public call, the call is received by the
Incoming Trunk Call Distribution method (DIL/DDI/MSN) which is assigned on the trunk.
