I'm not 100% sure this is accurate and has usability:

• Do we need the distinction for international numbers? Can we still enter local dutch numbers (eg: without country code) if a field has international validator?
• Do we support input of humanized numbers? Eg, with dashes and spaces for readability? Many people write their numbers in groups (06 1234 5678 or 020 123 45 67 or 020-1234567)

If we want make use of international numbers (imo we maybe only need them in the contact form) we need the distinction. When we enter such a number we have to use the country code indeed. Should I remove it and use only dutch numbers? @alextreme what do you think?

[alextreme]

I would recommend to only allow Dutch numbers (10 digits, no spaces, dashes etc). I'd prefer being too strict when it comes to data sent through to a secondary system.

[vaszig]

Removed international phone validator and now there is only the dutch one. I also added a method for spaces and dashes.

Couple of minor changes and we're good to go.
