all number normalisation / modification

Call numbers that are not stored in E.164 (e.g. in connected CRM systems) should be callable.

Specifically, there are customers who currently have systems in which the phone numbers are not entered correctly.

These customers cannot switch to Unify Office / Ring Central because the correction would require a lot of effort.

The requirement is to convert any phone number into a dialable E.164 format.


+49 (0) 8153 1234567 must be converted to +49 8153 1234567.

Almost all UC systems available in Germany / Europe support this function.
