Anybody have any ideas on this?  I dont know what to do and my new website
just launched yesteryday.

www.gafana.com

Go to the "Real-time sport scores" under the How It Works section.  You can
put your telephone number in there and it will call you.  Listen to the
message and hear what I am talking about.  Its strange though, *just* right
now I tried it and it sounded perfect...earlier this morning it jittered
every few seconds!
