From The Private Leased-Line Network Into The Public Network - ASCOM Ascotel 2025 System Manual

5.6.2 From the Private Leased-Line Network into the Public
Network
A PINX will route an incoming call from the private leased-line network on
towards the public network if the incoming call has a phone number
• with NPI = E.164 or
• with an exchange access prefix.
Phone Number with NPI = E.164
If the numbering plan identifier of an incoming call's phone number corresponds
to type E.164, the call will be routed directly to the route set under "Transit route"
by the incoming trunk group at a gateway or transit PINX.
The numbering plan identifier is set under "NPI" in the route configuration of the
source PINX.
[1] One and the same trunk group cannot contain both analogue and digital network interfaces.
