When dialling into the UK from overseas, you omit the leading zero - so, for example - say the number was 09 876 123 456 = from overseas you would dial 00 449 876 123 456 (the spaces are just for clarity). In your example, there are only 10 digits after the country code of 44 - indicating you have omitted a digit somewhere.
