Audioblogger!?

I signed up to use audioblogger. They gave me the number to call, and I tried calling it last night several times and today also. The # for me to call for audioblogging is 415-856-0205. I keep hearing "the number you dialed is not a working number". Why isn't it working??? :( I saw other people putting audio blogs on their sites, how did they do it? Did they give me a wrong number? I'm confused. I really want to try it out!
