Incoming phone number
The Multiple Subscriber Number (or MSN) is an ISDN feature that allows you
to have more than one directory numbers for a single BRI. Thus if you have
more than one ISDN devices connected to the NT1, you can set a specific
MSN to the USB ISDN TA so that it can accept an incoming call that is called
to the MSN.

For example, if you set an MSN as "123" the USB ISDN TA will only accept
the call with "Called Party Number's xx..x123. Where XXX denotes any
leading digits of the MSN "123" (Only the last digits of the numbers are
compared!) You can set up to 3 MSN´s for each port to the USB ISDN TA. By
default, no MSN is assigned. In other words, the miniVigor128 will accept all
incoming calls with every port.
