btw. This is only the German way to format numbers. And not even the 
latest standard.
Current standard would be (01 72) 1 23 45-678 or +49 (1 72) 1 23 45-678
 From right to left.
Phone extension as block and seperated by '-'.
Numbers get seperated every two digits from right to left.
Local are code the same. And put in brackets.
If international number is provided, remove 0 from local are code and 
put with + in front of brackets.

And of course every other country has it's own rules...

Have you ever seen a telephone number formatting in any address book 
that really works? Thought so... *g*

Worst. Some address books try to force these formats on you. So you end 
up not formatting them on input and live with whatever the address book 
app makes out of it.
And phone users never for,at their numbers, because the input mode for 
numbers usually only allow numbers...

So, i don't belive much in good looking numbers. They fail in real life.
