The pattern is
2{11-15,a-d}5
.
Numbers matching the pattern are
2115, 2125, 2135, 2145, 2155, 2a5, 2b5, 2c5, 2d5
.
•
Use an exclamation point to exclude a character or a string from a set.
Example:
The pattern is
2{11-15,a-d,!14,!c}5
.
Numbers matching the pattern are
2115, 2125, 2135, 2155, 2a5, 2b5, 2d5
.
Please Note:
You can use the wildcard
?
within the braces, but not
*
. Thus,
{12-104,15?,36?}
is a valid pattern, whereas
{15*,36*}
is not.
Please Note:
The symbol
!
cannot be used to exclude a range of symbols. For example
2{15-60,!23-32}
or
2{15-60,!23-
!32}
are not valid patterns. To valid pattern will be to
2{15-22,33-60}
.
[]
The same as above with the exception that character ranges can include single-digit/character elements only.
Example:
The pattern is
2[1-5, a-c]5
.
Numbers matching the pattern are
215, 225, 235, 245, 255, 2a5, 2b5, 2c5
.
\
Precedes a control symbol (
*
,
?
,
-
,
!
and
,
) to indicate that it is used as an ordinary character, not a wildcard.
Example:
The pattern is
1\*[1-3]
Numbers matching the pattern are:
1*1, 1*2, 1*3
Please Note:
Patterns cannot be prefixed with the
*
symbol. The system considers the patterns starting with
*
as feature codes
and does not parse them through the Call Routing table.
Best Matching Algorithm
All calls through and within a Quadro are made according to call routing patterns that specify a destination based on a dialed number. When a user
dials a number to make a call, the Quadro matches the dialed number against the existing patterns that are specified in the Call Routing table. If the
dialed number matches only to a single pattern, this pattern will be used to set up a call. If several patterns have been found to match the number,
the Quadro uses the Best Matching Algorithm to prioritize the matching patterns. Once the patterns are prioritized, the pattern with the highest
priority will be used as a preferred route for call setup. The successive patterns will be used only if the destination specified by a higher priority
pattern is unreachable.
To prioritize the matching patterns, the following criteria are sequentially applied to matching patterns. The criteria are ordered by their priorities:
Each consecutive criterion is calculated only for the patterns that take the same value for the preceding criteria: that is Criterion 3 is calculated only
for patterns that take the same value for Criterion 1 and Criterion 2.
Criterion 1
The presence of asterisks (“*”) in a pattern
The patterns without “*” have a higher priority.
Criterion 2
The total number of matching digits/symbols inside and outside the braces/brackets
The more matching digits a pattern contains, the higher its priority.
Criterion 3
The number of matching digits/symbols outside the braces/brackets
The more matching digits outside braces/brackets a pattern contains, the higher its priority.
Please Note:
This criterion is used only if several patterns take an equal but non-zero value for Criterion
2.
Criterion 4
The total number of question marks (‘?’) inside and outside the braces/brackets
The more question marks a pattern contains, the higher its priority.
Criterion 5
The number of question marks (“?”) outside braces/brackets
The more question marks outside braces/brackets a pattern contains, the higher its priority.
Please Note:
This criterion is used only if several patterns take an equal but non-zero value for Criterion
4.
Criterion 6
The number of square brackets (“[]”)
The more brackets a pattern contains, the higher its priority.
Criterion 7
The number of braces (“{}”)
