Configuring a Voice VLAN on GS1915 8/24 EP Switch

NigelD

Reading the User Guide (UG) [Version 4.70 Edition 5, 12/2024] and online posts for Voice VLAN is causing some confusion.
The configuration of OUI is straight forward but what is required beforehand is not, [at present]

I have a Peplink Router with networks 1.1 and 10.1, the GS1915 switch configured for 2 VLANs (1 & 10) all working as required with segregated data (Office on 1.xx vs Guests on 10.xx)
I wish to ensure IP phones in the Office have a priority re quality. (ie Voice VLAN)

Do I need to create a network eg 99.1 in my router and a static 99 VLAN in my GS1915 switch, or will the Zyxel Voice VLAN setup handle phones based on OUI and use VLAN 99 without the former config required? If so I assume the IP phone will still have an ip address of 1.xx

The UG on page 123 for Static VLANs states [Note: Do NOT add a VLAN ID that has been used in the Voice VLAN Setup]. Online examples (different switches, but the UI looks the same) do create a Static VLAN for Voice before then, enabling & assigning a Voice VLAN and configuring OUI, hence the confusion.

Can anyone advise re GS1915 switches for Voice VLAN setup?
TIA

You do need to create a static VLAN ID 99 first and configure Voice VLAN to 99.

Thanks, I have created the VLAN on the router and switch. Successfully connected a laptop and an Access Point, the latter handles wifi on .1.xx and 99.xx (I now know the config is good, re tagging)
I am waiting for our IP Phone provider to advise how we can update the phone to be VLAN aware and to use VLAN 99.

Hi @NigelD,

Sorry for the late reply!

We confirm that the proper configuration steps are to first create a static VLAN ID, then assign it to the Voice VLAN. We apologize for any confusion caused by the User Guide (p.123) and Handbook (p.237). We will revise the wording to ensure clarity.

We appreciate your patience and understanding.
