VDV21 and QoS?

Posts: 26 · Posted: Tue Dec 30, 2008 2:27 pm Post subject: VDV21 and QoS?

I experience voice quality issues when I have heavy LAN traffic, so my first thought is to isolate the VDV21 from the LAN. Currently all traffic passes through the ISP's gateway device (gateway, router, switch, DHCP), something like this:

gateway - wireless bridge - wireless LAN
- VDV21

A colleague suggests passing all of the LAN traffic through the VDV21 and letting its QoS handle things:

gateway - VDV21 - wireless bridge - wireless LAN

I'm curious if this is a viable solution?

My idea would be to isolate the LAN on a separate network segment:

gateway - router - wireless bridge - wireless LAN
- VDV21

the drawback being the added complexity of the network.

Does the VDV21 even do QoS? Can it handle massive LAN traffic, or is it best left to handle voice traffic only?

Thanks!

Your colleague's suggestion is viable. The Vonage boxes have QoS to the extent that they always favor phone traffic. The sticking point in the past has been that the typical Vonage box couldn't handle heavy traffic across your LAN even with no phones in use, and this would lead to problems with the setup proposed. However, the newer Vonage units may have gotten past this. I've certainly been hoping that that would turn out to be the case. I'd give it a try and see how it goes.
