If you are able to get a standard Subscriber Dialling Code (STD) number for a company in the UK, and the switchboard operator give you an 0870 number - or similar - to get through to the department you are wanting, then just say to the switchboard "I am calling from outside the country", and they will put you through to the correct depatment instead!

If they say the "0870 number will work from wherever you are" - say no it won't, and they will then put you through!

It works for me most times!

When you get through to the department you want THEY won't know it has come through via their switchboard!
