Brian Roberts, CEO of the largest cable company says that Comcast’s voice-over-Internet-protocol system should be 100% built by mid-2005, and the company is already testing the VoIP service in three markets. Roberts says Comcast’s VoIP calls will travel to its switching office and back over a private network to the call’s recipient. Comcast VoIP will not be transmitted over the Internet. In other words, it could be flying over Level 3′s network, or AT&T network.

  1. Hey OM, put me down for COMCAST to use Level3!!!!

    I know you might not beleive me since if somebody says “”VOIP” , I automatically ASSOCIATTE my baby Level3 with voip but soon, MOST all will do the same as me-Its Level3!

  2. Most folks talk about Voice Over Internet and mean that between the user and the switch is the public internet. Cable MSOs run PacketCable softswitches (see http://www.cablelabs.com) which means that between the user and the switch is a private IP network. This setup would mean that quality of service can be assured between the endpoint and the switch. If a company with this setup uses Sprint, AT&T, MCI, Level3, etc., they are probably doing it for PSTN access or long distance.
