Ring Central
From Halo
The cover of the September 2007 issue of WIRED Magazine features a prominent image of the Master Chief with small bits of overlying text. One bit of text was a phone number (888-778-5672). When dialed, a message says that the number is out of service, then proceeds to play a promo for the ficticious telecom compnay Ring Central. Some additional speaking can lightly be heard in the background during the promo, but it is unknown at present what the audio says.
