actually, I agree with both dpiehl and usa2k
If you are moving from PSTN you probably haven't had a need to access telco's website more than a few times a year (other than view your charges). So, ugly website wouldn't be the reason that prevents you from switching.

However, VOIP is much more than cheap PSTN (annoying Vonage commercials notwithstanding). I love FreePBX interface, but obviously it's a huge overkill for residential service. However, OBi control panel ("expert pages") is something to emulate. Even if you take away VSP pages that are maintained by VOIPo and locked - there are still numerous "user" settings that are exposed in clear and fairly logical manner.

Tim is correct, that it is always a matter of priorities (or ROI). From that perspective, I am sure there are people who appreciate the difference between "black list", "disconnect", and "busy signal" as call route action. However, whoever decided to implement this functionality before improvements in website UI needs some additional training...
