GREP to keep telephone number from breaking

[JE_D+P]

I'm a recent GREP crusader and after a few weeks or working with it, some of it is sinking in and starting to make sense. I'm creating a master template with paragraph styles and one of the many things I'm using GREP for is ensuring telephone numbers don't break over lines. I thought I had solved it but

(\d+ \d+)+

isn't cutting the mustard.

My telephone numbers will never be separated by punctuation but would need to account for several european/regional formats. Example formats could be; 0 00 00 000..., 0000 000 000, 00000 000000, etc. The telephone numbers could appear in the middle of paragraphs too.

I've tried quite a few variations now and I'm not sure where to go - any help would be appreciated!

EDIT: Well I feel stupid now but I thought this might help someone else. I fixed it with;

(\d+? \d+?)+

\d[\d\h]+\d

Thanks. I'm curious as to what your expression is better than my edit?

Didn't you notice that your regex doesn’t work (expectedly) on your own - second - sample?

Michel's one is much more flexible and universal, and still safe.

Nope, but I have now! Thanks to both replies.

Not exactly! … This kind of code will work … [even if I don't like it!]

But it's just a personal comment.

Best,

Michel
