I hear that Covad is the only facilities-based VoIP provider and can therefore offer better QOS prioritizing of VOIP versus data and security. Is this true?

Any broadband provider that also provides VoIP services has better control over the prioritization of traffic within their network. They can also implement certain security policies within their network. An important thing to note that if someone calls a destination outside of the service provider's network, that the service provider no longer has complete control over the traffic and quality again may vary. I believe there are other providers offering VoIP that also own the broadband facilities. Verizon is one example that comes to mind.
