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.
