Technically, it meets VoIP requirements as per callcentric and their 
recommended website for testing that:  http://myvoipspeed.visualware.com/, 
which came back with:

Glossary of Results 

I use a "slow" or "lite" speed service with a cable modem.  I'm still 
working with callcentric tech support, who are quite helpful, but I'm 
dubious as to the outcome.

I had a PVR from the cable company but it would periodically basically 
stop working, the image would be completely pixelated.  A technician 
inferred that there was a splitter somewhere because he wasn't able to 
test our line, but he did have someone come out and replace parts outside 
the residence, however, those parts turned out not to be broken.  I 
figure that the wiring in the house just wasn't done properly.

I might upgrade the service to at least test whether that helps.
