Currently, users can also enter letters and special characters in the phone number input field. This of course leads to the fact that the telephone numbers cannot be processed by the system and thus unnecessary errors are caused. Therefore, it would be desirable to check the specified number before processing.
An optimum would be if special characters normally found in telephone numbers (such as + - ( ) and /) were allowed and taken into account.
For example: The given phone number +49 (0) 175 123 456 should be interpreted as 0049175123456. A phone number +1-713-548-1700 as 0017135481700.

Agree that there should be syntax validation for the phone number, but in reality it should be kept as +xxxx prefix, not all countries use 00 for an international prefix, but the + is a globally accepted international identifier.
