Using broadband and dial up from same laptop

Hello everyone

I am asking on behalf of a friend if you can assist on the following problem.

He has just installed Sky broadband in his home but needs to use Wanadoo dial up at work. Is it possible to do this ? If so how can he set it so that there is no conflict and dial up does not keep asking to start when hes home and and it recognises that he is either home or office.

Thanking you in advance for any assistance.

Your best resource would be to contact Sky Broadband if this is possible. It may conflict it all depends on the company, and if this will work. So does he work from home?
