A quality call is more than voice

Everyone focuses on voice quality as one of the key metrics of VoIP service, but they frequently make it sound like that's the only metric. It isn't. A call lasts from off-hook to on-hook, and there's more than the quality of sound. Does a dial tone appear immediately? How long does the call take to set up? Does the call go through, hit a block or get lost in the ether? Can it connect to 800 service or 911? Do IVR systems work? Voice quality may be terrific, but if your customers have to wait for a dial tone or try three times before a call goes through, you haven't engineered your network adequately.
