M2 Source Transformation
Source Transformation rules
Source Transformation rules are used to manipulate Source (CallerID) number (cut prefix, add prefix). Only number part of CallerID will be changed. Rules can be set in Termination Points or Origination Points Source Transformation input field. There are 3 different Source Transformation rules:
1. Add prefix
To add something to every number, just enter what to add.
2. Cut prefix
To cut something from number, write - (minus) character and then what to cut. For example -00 will cut 00 from the beginning of number (only if number starts with 00).
3. Replace prefix
To cut something from number and add something else (replace), write - (minus) character followed by what to cut, then + (plus) character and what to add. For example -00+8 will cut 00 from beginning of number and add digit 8 in front (00 will be replaced by 8).
It is possible to define multiple Source Transformation rules in one single line. It is done by separating rules with | character:
Rules are checked in the order they are written and first matching rule will be applied. If one rule is applied, then other rules will be skipped. This means that some rules do no make sense, for example 00|-6+370 rule will always add 00 in front of number and second rule will be skipped.
The number of rules is limited only by the length of input field (255 characters).

|86123456789||00||0086123456789||simple rule just adds 00 in front of number|
|003706123456789||-00||3706123456789||if number starts with digits 00, then cut them|
|003706123456789 or +3706123456789||-\+|-00||3706123456789||cut + or 00 in front of number|
|86123456789||-8+370||3706123456789||cut number 8 and add 370. If number does not start with 8, then nothing will be added|
|03706123456789||-00+370|-0||3706123456789||Source Transformation contains multiple rules but first rule is skipped, because number starts with 0 and not 00. Second rule is applied and 0 is cut from number|
|3706123456789||-00+370|-0|+||+3706123456789||Source Transformation contains multiple rules but first and second rules are skipped. Last rule simply adds + to the number|
|86123456789||-8+370|00||3706123456789||Source Transformation contains multiple rules but first rule is applied and other rules are skipped|
|86123456789||-8+\+370||+3706123456789||if number start with digit 8, then cut it and add +370. Note that + is escaped by using \ character|
