How do you make a phone call to Scotland?

The international dialing code for Scotland (and the rest of the UK) is +44. Faxes can be sent and received in the same way as in any other country.

EDIT:

If dialling from the US or Canada, dial:

011 44 + fax number

If dialling from other European countries (for example France or Germany) dial:

00 44 + fax number
