6. 4. 4 Call to the private Leased-Line Network
The call to a fixed network PISN user is routed via the private leased-line network. The
PISN user must be created in the internal numbering plan. The caller dials the PISN
user number.
The routing information on the PISN users is allocated to the user configuration and in-
cludes the route to be used and the phone number under which the destination user
can actually be reached.
Normally a PISN user in the fixed network can be reached directly under his PISN
phone number, which means that no other phone number needs to be entered in the
user configuration.
