Pisn With Different Regions - ASCOM Ascotel 2025 System Manual

PISN with different Regions

A PISN can be divided into several regions. Each region is identified by its regional
prefix.
Subscribers who call a subscriber in a different region first dial the prefix of the
destination region, then the internal number of the subscriber they want.
Their specific regional prefix is specified in the internal numbering plan of each
PINX.
The organization of the numbering plans does not depend on the PISN topology.
