I am using ADSL for the first time in Europe (Greece). The internet signal is terrific (ie it works as advertised). However, I cannot get my phone to work. I've tried splitters and filters. Do I need a special phone? This is over POTS - not ISDN. I'd be happy if someone came back with the pin configs for RJ11 and 12. I've tried my local phone company office - they are very nice. but that's all. Help! David
