Before enabling the Dial Plan Range feature in an enterprise system, ensure that all Session Manager installations are of version 6.3.4 or later.
Using a Dial Plan Range, you can specify number ranges in the Session Manager Dial Plan.
A valid range has the following characteristics:
Two integers separated by a colon (:)
(Optional) A plus sign (+) can precede the numbers. If one number begins with a (+) sign, then the other number must also begin with a (+) sign.
The number to the left of the colon must be numerically less than the number to the right. These numbers cannot be equal.
The numbers on the left and right of the colon must be of the same length.
Note:
The Global Settings Dial Plan Ranges must be enabled on the Session Manager Administration page.
The valid pattern format is [+0-9][0-9]{0,23}[:][+0-9][0-9]{0,23}. For example, +493420479242000:+493420479242999.
You can enter a range that is a subset or superset of an existing range or pattern. The smaller range is a sub-range. Sub-ranges have the following limitations within the same location and domain:
Two sub-ranges must not match each other.
A sub-range must not match a pattern.
A sub-range must not cross the starting or end of another range.
Dial Plan Range Example
If the Dial Plan Range is 5000:5499, you can specify the sub-ranges as:
5002:5011
5000:5499 and 5492:5499, where the end of sub-range and range match.
5000 (single entry) and 5000:5009, where the beginning of sub-range and range match.
The sub-range 5300:5555 is not valid because the sub-range crosses the end of the range.
Note:
When routing, Session Manager performs more efficiently using a smaller range rather than a larger range or longer pattern.
