[Wylug-help] Recommendations for corporate dial-up?

[lists at mungewell.org]

Hello all,
again I'm tapping you guys for information... and this one isn't really
to do with Linux. :-(

Can anyone recommend a corporate dial up solution, we want to have a
free-phone number that our road warriors can use with costs billed
directly back to the company.

No services (web/mail) are require, just the connection so they can VPN
into head office.

Thanks,
Simon.
