Answer 1

You can use

^(?!\d{1,6}$)(?:(?:\+43|00?) ?)\d+(?:[ \/–-]\d+)*$

See the regex demo.

Details:

• ^ - start of string
• (?!\d{1,6}$) - the string cannot consist of just one to six digits
• (?:(?:\+43|00?) ?) - a sequence of +43, 00 or 0 and then an optional space
• \d+ - one or more digits
• (?:[ \/–-]\d+)* - zero or more repetitions of a space/slash, em-dash or hyphen and then one or more digits
• $ - end of string.
