Apparently CallVantage had an outage yesterday. Since I was traveling I didn’t know until a chat with Yak’s Dave Hurwitz. He told me my number was giving some kind of not available message. I tried CallVantage’s web site, had no luck so I dialed my number and heard what he heard.
But the service was back up within the hour so I figured it was just an outage. Tom Keating has more details.
