For some sort of update on this sitch. I received the Mot ATA from vonage, and proceeded to hook up my Philips DSR704 to it. it tried to dial out, but no dice. I checked the vonage bandwidth setting, and tried several of the prefixes to no avail. For some reason the 9600 setting would appear to make the most progress, but would still give a "can not connect" error. I am going the route that dallas4u tried, and ordered an external kit from eksys.com. hopefully I will have that by the end of the week and can see how that works.
