• Diva SIPcontrol's number normalization function does not remove outside access digits like a PBX can for

external calls. If Diva SIPcontrol needs to behave like a PBX with an outside access digit for external calls,

use the address map functionality in combination with a route.

Number Modification Using Regular Expressions

Diva SIPcontrol organizes regular conditions into address maps, and each endpoint or route can be assigned

one map. Each address map contains a number of regular conditions together with the respective output result

strings. This helps to ensure that virtually every required manipulation scheme can be configured.

By using separate address maps instead of rules embedded into the routes and endpoints, it is possible to share

the same settings across different objects. For example, if several PSTN interfaces are connected to the same

PBX, they will most probably be configured with the same settings. Therefore, these PSTN interfaces can share

an address map that Diva SIPcontrol lets you assign for each individual controller.

Diva SIPcontrol uses the style of regular conditions used by Perl. Most tutorials and how-to's covering Perl regular

conditions can apply to Diva SIPcontrol.

Common Conditions:

Character Meaning

. Matches any character

^ Matches the beginning of an address

$ Matches the end of an address

\+ Matches the plus sign ("+")

* Matches any number of occurrences of the previous character

{n} Matches the previous character exactly n times

{n,m} Matches the previous character between n and m times, both inclusive

( ) Marks a sub-condition to be referenced in result string and also groups sets of characters

| Alternate operator, matches either the left or right sub-condition

[ ] Matches any character given within the square brackets, i.e [123] matches either 1, 2,

or 3, but not 4, 5, or 123.

(?i) Considers case for everything after the tag.

For example "username@(?i) hosthame.tld" matches "username$HOSTNAME.TLD" and

"username@hostname.TLD", but not "USERNAME@hostname.tld".
