Phone Number Validation

Hello, I am using the library for checking the validation phone number
this number '0155208386' isn't a valid phone number in Egypt because is 10 characters, not 11 characters, but the 'isValidFullNumber' returns true, and this wrong

Start by locating the isValidFullNumber implementation and tracing how it validates Egyptian numbers. Reproduce the reported case, 0155208386, and add or update coverage if the project has an existing validation test location; done means this 10-digit Egyptian number is rejected while valid 11-digit numbers continue to pass.
