Configuration
The example shows a normalizing rule for long-distance calls. Fundamentally, the setting up of a rule is sup -
ported by a graphic interface, which helps to set up the rule correctly. More complex formulas will have to be built
manually though.
Image 3.32: Building a normalization rule
This rule is activated for all numbers that start with a 0 and are in total 6 digits long. One digit (the lead -
ing 0) is then eliminated and the numeric se49 is added at the beginning. This makes 0301234567 into
+49301234567 and therefore the required the E.164 format. All other rules need to be built in the same way. Mind,
that the rules are processed from the top to the bottom, until a match has been found.
A rule for international calls could be constructed similarly (Difference: starts with two 00‘s, those are elim -
inated). This rule should be located above the long-distance rule, as the long¬distance rule would also be trig -
gered because of the first 0. That would lead to the number 0043198765 being converted into the wrong number
+49043198765 instead of +43198765. Alternatively, the long-distance calls rule could also be constructed that way,
that not only the first digit has to be a 0, but also that the second digit cannot be a 0 as well („Starting digits“ would
then be 0[1-9]).
Routing
Last, it has to be secured, that outgoing calls are directed via the configured gateway. For this, a connection will
have to be made between the „PSTN Usage“, meaning the call classes like internal or local, the „Voice Policy“ as -
signed to the users and the „Route“, meaning the path to the gateway.
This process will not be explained here, as there is a detailed explanation by Microsoft available. This mecha -
nism allows for a flexible definition of calling allowances as well as „least cost routing“.
