We note that users have been posting concerns for several years but Sonic's response hasn't been is not entirely clear, much less transparent.
Our answer is pretty clear and transparent: If you have issues with your service you should reach out to our Support; be it over the phone, email, twitter message, facebook message, or a private message here on the forums. Each issue is going to be different. VOIP issues in particular can be caused by faulty equipment, bad wiring, packet loss to the modem or adapter, upstream saturation, etc. There's no magic switch that we can flip to fix all potential problems, but if there were that'd be pretty sweet.
