UK online problem!

I have a HK Dreamcast (as you know) with a brittish PAL modem. I'm using Dream key 3.0 through a boot disc (1.1 Utopia or something?) The problem is that when ever I try to connect it dials for about 20 seconds then tells me to check that my phone line is attached to my modem! Any help would be greatly appreciated. Thanks
pickup the phone and see if its actually dialing when you tell it to, and also if its getting a bt error (voice message saying the number is wrong or anything

btw, if your using the bt click number, change the username/pass to something other than sega/sega in the settings, since it appears to connect better that way
