If you live in western Canada for $10 more a month Shaw Cable will activate a QOS (quality of service) option to improve the voice quailty of Vontage or any of the other internet phone services that use the public internet.
Shaw also has their own digital phone service which does not travel over the public internet to access a telephone switch and is not subject to this charge.
Last I heard Vontage was going to the CRTC (Canada's version of the FCC) to have Shaw remove the QOS charge.
I have some friends that have the Shaw telephone service and other than a few outages the voice quailty seems to be ok when I call them.
