Good day good folks.
So our office is upgrading a decade old infrastructure and moving from completely unmanaged networking and traditional telephony to managed network and IP Telephony. We have two Dell PowerConnect 5400 series switches that are going to be installed in the lower and upper floor. There will be 3 VLANS - one for main network (workstations, printers, NAS, etc), one for IP cameras security system and one for IP Telephony/VoIP. The Dell switches provide two options; VLAN and Voice VLAN. As per my understanding, Voice VLAN is useful when you want to prioritize voice packets over data packets when using the same trunk (PC --> IP Phone --> Switch). But in our setup, all our IP Phones are going to be installed on separate port each and no PC will be connecting to the IP Phones. So my question is should I still use Voice VLAN for the IP Phone subnet or just simply a normal VLAN as our Phones and Workstations are on different ports each. Thanks.
