Out network is all out of IP address due to adding voip phones on the network. Our phones are wired in-line with our PCs so options are limited.  Our SonicWall vendor informed me that i can configure a managed switch to hand this and has configured the router for a separate IP stack for our phones,  192.168.30.X with ip addresses assigned to each phone MAC address. They set up VLAN 30 for these devices. I have not worked with managed switches before. Could someone out there help me with how to configure this switch to do what they are asking for? I have followed the instructions for setting up a Voice VLAN but everything I am seeing is just to give the phones data priority over the PC data, as apposed to pointing them to a new IP stack
