It depends on how the VLANs are configured. If phones and PCs are on separate VLANs, your phone won’t automatically share its network connection with the PC unless you explicitly set up a port group or bridge to combine them. A switch can indeed manage multiple VLANs from a single port, so you shouldn’t be completely blocked—just make sure the routing and bridging settings align with your needs.

The two ports are typically laid out in a dumb switch configuration. Traffic moves freely without VLAN filtering since there’s no filtering involved. I’m not very familiar with VLANs, but regardless of setup, you can route different VLANs through the same phone line.

Here’s a refreshed version of your text:

Welcome to the intriguing (and sometimes frustrating) world of the “voice VLAN.” If your switch supports this feature on its ports, here’s the process: 1) configure the port with either an untagged or access VLAN you want the device to connect to. 2) assign a specific VLAN name to the “voice” VLAN for the phone. 3) during startup, before DHCP is assigned, the device will scan for LLDP messages from the switch. These messages contain the voice VLAN information. 4) when it detects a voice VLAN in the LLDP data, the phone will apply that VLAN as a tag. Traffic from other ports remains untagged. Some switches require you to mark the voice VLAN as tagged, while others automatically include it. Check your switch’s documentation or user manual for details on “voice VLAN.”
