I've done some of the larger designs and installations of AVVID in the world, and especially North America, so let me know exactly what you need. I'm not badmouthing Cisco, but they config a lot of the AVVID stuff wrong, and they invented it! Cisco is good at data implementations, but it's hard to find a good guy in the field who can give good advice on the configs and HW involved.
Basically, the AVVID server components go where any other server goes. VG200's go where ever as well, but keep in mind there are two types, the Vg200 gateway and the Vg200 DSP farm. As for implementing the voice first and video second, keep in mind, once you have a good, solid data infrastructure in place that can handle QoS, the video phase is quite easy. Bandwidth over the WAN may be your biggest issue at that point. ""Tom Scott"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I'm reading Priscilla's "Top-Down Network Design".
