I have been using Skype as a landline pretty exclusively for the last 6 months, but the quality of the service has been degrading rapidly. Today, I called Samantha from the office and she said it sounded like I was calling from inside a tin can.
So, on a recommendation from a co-worker, I am giving Gizmo a try. Pretty immediately, I noticed a quality improvement over Skype, and people on my conference calls said it was much better.
So, if you want to reach me, try spierzchala on Gizmo, or +1-508-635-4420.
And Skype, let me know when your quality improves.
