Thanks.
My boss wants to just plug his computer into the phone jack in his hotel room, dial without any input from him, and connect to our network. Any other option that requires more thought or inter-action from him is not acceptable! :-)
After two years of trial and error, we finally have a solution that is largely idiot proof. Remote Pipes provides the software and service, which makes local ISP dial-up numbers available all over the world. I call the hotel, ask for the number to dial to reach an outside line, program that in, and it is all set for him.
The area code issue is a new one (we discovered it while he was in the Czech Republic). Normally, it always dials the area code, but that didn't work in Prague:-( One more question I have to remember to ask the hotel people, who often rarely speak English. I prefer to get all my answers from sources other than the dawn shift at Shangri-La Hotels, Myanmar, Burma :-)
Thanks for the tip on Netherlands. I will add it to my list.
