Ok, I bought an external modem, made the cable, plugged it in and now it can't get past negotating (sp-1). I can get it to work about half the time on my landline but only about 1 in 100 on Vonage. Is there an init string or something that I should do to my modem? I have a US Robotics Sportster 28800 Fax Modem and also a SupraFaxModem 288 (which I am using cause it looks better). Is it also possible that some dial in numbers work better than others? If so, please post trouble free numbers so that I can try. Thanks everyone.
