When setting up SIP accounts from some telecom operators or registering with a PBX whose settings are not on our list
Server templates You may need to manually configure number conversion rules for outgoing calls.
Before sending the phone to a SIP operator, you may need to convert the number to its format. For example, in telephone numbers are often written with 8s, with brackets and spaces. For compatibility, it is better to convert such numbers to a standard format:
8 (926) 123-45-67 → 79261234567The essence of the necessary number conversion: remove spaces, brackets and hyphens. The number 8 at the beginning of the number must be converted to the country code, for example, for Russia it is 7.
This kind of transformation is done using one or more regular expression rules.
- There are 2 types of rules: those containing the = sign (equality) and those not containing it
- All rules are applied in turn
- We recommend using the ` (single quote) character at the beginning and end of rules to disable the possible conversion of part of the rule into emoticons.
