VoIP QoS

[mic]

Hi to all,

we have the following 4 VLANs:

• LAN - VLAN 10: 192.168.10.0/24
• WIFI 1 - VLAN 20: 192.168.20.0/24
• WIFI 2 - VLAN 30: 192.168.30.0/24
• VoIP - VLAN 40: 192.168.40.0/24

We need that the VoIP VLAN has the priority over the others. Our ISP connection is a 100/100 Mb/s. Our goal is that if the connection becomes saturated, the VoIP VLAN takes precedence over the others and, if possible, reserve for the VoIP VLAN, in case of band saturation, at least 15/15 Mb/s.

Thank you

Yes, I have read these two guides but, honestly, I have not understood how to adapt them to my needs. Also consider the fact that the VoIP Server is in the Cloud and its Public IP changes from time to time.

Thank you
