default, MSN function is disabled. If you leave the fields
blank, all incoming calls will be accepted without number
matching.
1-10 fields – Fill in the portion that is different with the own
number.
For example, the own number is 1234567 and MSN numbers
are 1234550, 1234517 and 1234582 respectively. You can
type in 1234567 in the filed of own number. Fill in 50, 17
and 67 on the fields of 1, 2 and 3 one by one without typing
12345.
Mapping to Phone Ports For loop through phone calls, you can assign Phone or/and
ISDN1-S0 as ring ports if incoming calls correspond with
settings on MSN number field.
There are ten internal lines (30-39) under ISDN1-S0 for you to
configure as dedicated line.
You can setup your ISDN
phone with one of these 10 different internal MSN
numbers. Transparent means
MSN on TE port can connect
to NT port without limitation on the number among 30 ~ 39.
Any means all the phones under ISDN1-S0 would ring.
If you choose Any as ISDN-S0 port, when the router receives
the incoming phone call with certain number for reaching
ISDN-S0, all the phone sets connected to ISDN-S0 will ring at
the same time.
Phone CLIR/CLIP CLIR means “Calling Line Identification Restriction”. If you
choose this item, we will not let remote side see your phone
number. Such function depends on environment that ISP offers
to you. Usually, hidden telephone number is not permitted
under many real circumstances.
CLIP means “Calling Line Identification Presentation”. Usually
the router will send "Own Number" to the remote side.
However Own number will restrict the router displaying only
one number on remote side. Vigor2820 series can connect up to
6
phones at the same time. Therefore, if CLIP is selected, the
external MSN numbers that you setup will be displayed to
remote side.
