Digit Map
Note:only Vigor2700 and Vigor2800 series VoIP Router support the Digit Map function.
1. Introduction
The Vigor2800V allows each call to be configured with a
distinct prefix rule. The prefix rule specifies how to interpret
digit sequences dialed by the user, and how to convert those
sequences into an outbound dial string.
2. Parameters
The prefix rule functionality is regulated by the following
configurable parameters:
- Prefix Number
The Prefix Number specifies a series of digit
sequences. When a user dials a series of digits,
each sequence in the prefix rules is tested as
a possible match.The matching sequences form a
set of candidate digit sequences. As more digits
are entered by the user , the set of candidates
diminishes until only one or none are valid.
- Mode
There are four modes that could be selected in
each prefix rule.
- None : This rule will not change the
subsequence of prefix numbers.
- Add : "OP number" would be
added in front of prefix number.
- Strip : Some numbers of prefix can be
automatically deleted when they match
with "OP number".
- Replace : Prefix number can be automatically
replaced with a different subsequence
of "OP number".

- OP Number
If you selected mode as "Add", "Strip"
or "Replace", The OP number will be
applied in this rule
- Min Len and Max Len
When a user dials a series of digits, each sequence
in the prefix rule is tested as a possible match."Min
Len" and "Max Len" specify the
length of dial number, but it's length don't contain
the size of prefix number.
- Interface
The interfaces, referring to the 6 SIP accounts,
specify the outgoing call of the digit map rule.
- PSTN (x)
- ISDN (x)
- VoIP1
- VoIP2
- VoIP3
- VoIP4
- VoIP5
- VoIP6

3. Examples:
3-1: The 4 interfaces are registered with SIP accounts
from different ITSP respectively. When you dial a number,
the number will be transmitted via the default interface.
The default interface is configured as VoIP 1.
The digit map is configured as below:
For example, we need to call FWD account 645479, we should dial 2645479, it matches the second rule, so
this call is transmitted via interface VoIP2 but not the default VoIP1 and the first number 2 is striped.
Of course, you may choose a complex number instead of 1,2,3,4.
3-2: Use digit map to simplify the dial number.
3-2-1: The first rule accepts the call using
03 as prefix number.
For example, "035972727", It matches
the first rule, and it's length ( Don't include
the length of prefix ) is 7 between Min_Len 6
and Max_Len 8, so SIP account1(VoIP1) will make
a phone call "035972727".
3-2-2: The second rule accepts the call using
886 as prefix number.
For example, "88635972727" would match
second rule and transmit "35972727"
as dial number by SIP account2. ( VoIP2 )
3-2-3: The third rule accepts the call using
04 as prefix number.
For example, "048993765" would match
third rule and transmit "886048993765"
as dial number by SIP account3. ( VoIP3 ).
3-2-4: The fourth rule accepts the call using
9 as prefix number.
For example, "95505234" would match
fourth rule and transmit "08005505234"
as dial number by SIP account4. ( VoIP4 ) |
