This is in no way a bang against cable Internet providers, but the 
customers that I've dealt with that use *any* other VoIP provider with 
cable always seem to have this problem.  Mainly with Comcast cable, may 
not be the same for you. I use (5) Vonage VoIP lines for my business and 
never have any problems with calls, voice quality, etc. I use Covad DSL, 
but this isn't a DSL vs. Cable kind of discussion so my input is that 
I've seen others with the exact same issue when using VoIP via Cable 
Internet providers.  Comcast offers their own VoIP solution which seems 
to work just fine (go figure).  I guess it begs the question, did have 
Vonage with DSL before you switched or after?

Thanks,
Michael
