VOIP without dedicated VLAN - experiences?

Hi,

our org is planning to move away from "good" old semi-analog phones to VOIP this year. I've been reading quite a bit about the requirements for VOIP over the last few days and the general consensus is that VOIP devices should be on a dedicated VLAN and subnet. However, unfortunately many of our access switches do not support 801.11q - so it looks like all phones will have to share their network with the standard endpoint VLAN.

We have enough bandwidth on most of the sites so we don't really have to worry about doing QoS and so on, which seems to be the main reason for separating phones from the rest of the network. Are there other reasons for separating VOIP from other data traffic? Have you deployed VOIP without separation before?

If it is necessary to separate VOIP from other traffic, we'll have a hard time implementing VOIP in the near future.

Thanks for your help.
