N2024P configuration for MS Lync 2013
We need to configure few Dell N2024P switches for Lync VoIP, in addition of the QoS DSCP global configuration do you know if Lync requires to divide the network in two VLANs or is not necessary and prioritizing the traffic via DSCP is enough for voice quality?
Here is the current scenario:
The Lync server is hosted by an outside cloud/VoIP provider, we connect the clients via Lync 2013 autodiscovery with no problems, the majority of the IP Phones are CX600 for MS Lync and the rest are CX300 USB phones or MS LifeChat 4000 USB headsets.
Each seat have only one Ethernet drop, the CX600 GB is connected to the LAN and the computer to the phone. In all other cases just the computer is connected to the LAN.
Thank you in advance for your help in this matter.

Daniel,
Thank you for your prompt response.
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.
Thanks again for your help.

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.
