I was wondering if anyone has much experience with QOS on VoIP. We recently installed a Vodavi XTSc and set up 2 sites with 2 Vodavi IP phones at each. The main site and one of the remote sites has DSL, the other remote site has cable. The bandwidth at all of the sites is a little tight and we realize the quality of voice is not there, we are trying to find some small routers and switches that provide QOS. Its a small customer who does not want to spend allot more to replace network equipment.
Any info on QOS, smaller routers for cable/DSL, or similar setup over the internet would be extremely helpful.
Vodavi wasn't able to recomend any particular devices, just specs needed.

Thanks.

I have a few ip phones out there, but all of my end users are using cable instead of dsl. I believe that LinkSys has some QOS settings in the setup but i could be wrong.
