I thought VOIP was cool and stuff. I used the SkypeOut feature

But

When Comcast goes to shits you can forget about VOIP. It's horrible, especially when one of the nodes nearby was so overloaded it would return pings of 150ms which made the VOIP stutter and grable.

Untill they institute laws to prevent the ISPs from throtling VOIP traffic and degrade it on purpose I would stick to cell phone. I think some ISPs are even starting to say that if you wanted your VOIP to work at maximum you should signup for one of their packages instead
