Multiple Subscriber Numbering (MSN) – In
Euro-ISDN, and some country specific
variants, it is possible to have several ISDN
numbers for the same BRI or PRI
connection. This feature allows you to
assign different ISDN numbers to different
applications, or different physical
equipment, e.g., modem, phone
instrument, fax machine, etc. When
specifying MSN Numbers, don’t enter the
whole number, but only enough of the
right most digits so that the numbers
allocated to the line can be distinguished.
Right now, a maximum of eight MSN
Numbers is supported.
For all ISDN incoming calls, when the
dialed digits are matching with the
configured MSN number, then, if the Dial
Number corresponding to the matched
MSN number is present, then using that
Dial Number an IP outgoing call is made.
Otherwise, for the matched MSN number,
if no Dial Number is present, dial tone is
provided to the user to dial the actual
digits with which to make the IP outgoing
call.
