I m trying to create a voice vlan for a static ip using the omada controler but the guide in the site can't help me because  I can't find a QOS tab in the controler pages.

Till this point I have done the following:

Created a vlan called SIP

Enabled the vlan using the config tab of the switch

Changed the port 7 to SIP VLAN

And entered the port profile to do there changes

1. First of all the port profice doesn't save anything. Each time I enter it shows the default settings

2. Do I need to port forward the data from 1.20 ( the phone) to Wan1 Which is the providers Wan?

3. Do I need to do anything else?

I can\t find a QoS tab anywhere or the UOI config page that shows in the guide.

Thanks for your time.
