I think we have enough bandwidth for our LAN and WAN, all our switches, phones and workstations are running at 1GB and our ISP is a fiber based circuit with 100Mbps download and 100Mbps upload for 50 users.
Our network access to shared resources is great and our web browsing with heavy data entry in many different portals is fast too, uploading/downloading data and documents to two of our major cloud providers is great too.
Because we are suffering Lync poor voice quality I want to make sure if I need to segregate the network with two VLANs or just prioritize the voice traffic.
I went and configured LLDP and Voce VLAN on the ports with a phone and computer, also setup those ports with IP-DSCP 46 and make it Priority 5. When I tried to separate Voice VLAN 10 and Data VLAN 5; I can't get an IP via DHCP, I went back and made both Voice and Data VLAN1 and it leases an IP for the phone and one for the computer, but the quality still really bad, in some cases the phone displays "Poor network quality".

I found the solution to the DHCP problem here: http://blog.schertz.name/2011/01/manual-vlan-configuration-for-lync-phone-edition/ however it looks like is not 100% certain will work.
My DHCP server is running in a Win2003 standard server.
Any help will be greatly appreciated.
