    Hello.. My roomate suggested we get Vonage...

    Comcast is my service provider.

    My concern is playing games such as half life when a phone call comes in.

    Im wondering if it will affect my pc download speeds and/or gaming latency etc... or if the service uses specific frequencies (multiplexing).

    Does anyone have any experience with this on a home net.

    thanks.

    Works great for me. My understaning of QoS is that that one service will only get the bandwidth it needs in order to function properly instead of hogging it all.

    Well, if you have QoS and a VoIP service, it will affect bandwidth. The VoIP traffic, being UDP packets and real-time are given priority over other traffic. That's not to say that the other traffic will suddenly cease, just that if there is VoIP traffic and other traffic queued to be sent, the VoIP traffic will go first.

    Vonage VoIP uses about 90kbit/sec bandwidth, so it will only take 10-15% of your upstream throughput, and a small fraction of your downstream throughput on a typical Comcast 6000/768 account. If you don't mind lower voice quality, you can cut the Vonage bandwidth usage to as low as 30kbit/sec in your configuration.
