Phone question

I am living in France at present. I have just taken delivery and connected up to the net via a livebox from Orange. I also have a pohne. This plugs into the live box but the actual phone numbers starts with 0297 which is a local french code. My question is, is this a France telecome landline of an internet phone. I believe it is a landline phone. Just need to know prior to applying for 0044>co.uk services.thanx. Colin
