Dial Plan Ranges

Note:

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.
