Apparently Shaw now offers a feature that will allow you to prioritize the packets that vonage uses so that during peak times it won't drop calls or degrade quality, but if you have to pay shaw extra so that you can use vonage you might as well just use Shaw's digital service anyways
I've had Shaw digital for well over 2 years now and have never had any issues, I've never had it go down or even sound funny even once, its a pretty good deal and its also pretty nice to know how much your phone bill is going to be every month no matter how many calls you make
I do have one question though about vonage, did you have to pay a cancellation fee when you dumped it? I read through their fine print at one time and noticed they have a ton of fees if you cancel, curious to see if they actually enforce them
