MSN

Multi Subscriber Numbering (MSN) is a service which you buy
from your local ISDN service provider. MSN allows the user to
specify which service an incoming call will use, based on the
phone number dialled by the calling party.

MSN Explained

When an ISDN call is received, the router is presented with two
numbers; the calling line identifier (CLI), which is the number of
the caller, and the number which is being called (called number).
When you buy ISDN MSN from your service provider, your
original telephone number becomes 10 telephone numbers. For
example, if your original telephone number was 123450, the
number is now broken down into the following numbers:
Now, when an ISDN call is received by the Nautica 200, it is
presented with the CLI of the caller and a number representing
the MSN required by the caller. The MSN portion of this
information changes depending on the service provider you are
using. Some providers will show only the MSN (0 to 9), others
will show two digits (00 to 09), and still others will show more
digits.
