Hi! I am looking for a best practice soulution for my 3CX phone system, today i've got about 6 members on the 3CX server and we are constantly bothered with echo and scrathing noises. - I suspect that it is our networking that may be the problem, we connect our phones to the switch where all our servers are connected, we also have our computers connected trough our phones (2 port switching). - I wonder what best practice is, QoS and VLAN, or is enough with just the QoS to all of our phones, and we dont have to seperate the phones from our server network with VLAN. Code: Internett --> Router --> Switch -QoS-> 3CX server --> Computer --> Computer -QoS-> Phones -QoS-> Phones -QoS-> Phones Or Code: Internett --> Router --> Switch -QoS/VLAN 1-> 3CX server -VLAN 2-> Computer -VLAN 2-> Computer -QoS/VLAN 1-> Client -QoS/VLAN 1-> Client -QoS/VLAN 1-> Client If someone has the answer for the best practice when it comes to this kind of setup.
