Windows DHCP/DNS + Multiple VLANs

Hello,

I wanted to separate our VoIP traffic in our office but I'm having a hard time understand the whole concept.

I run a Windows 2016 DHCP server with a single scope ATM (10.10.1.0/24). I have a Cisco RV082 router set as DHCP relay to the Windows DHCP server.

I have a UniFI 16-Port switch as my main switch. Other switches including the VoIP PBX is connected from here.

I want to create a separate VLAN for the VoIP. Been reading the net and found some articles that I should create a new scope on my Windows DHCP server. So I created a new scope, 10.10.4.0/24.

And I'm lost.. what should I do next? Do I have to do something on the router?

Thanks.
