I think it was a Youtube video that I watch from Tom, where he was configuring a VoIP phone to work with a computer on a different VLAN connected to the Phone.
Sonicwall —Unifi_48PoE-----YeahLink---------DELL Computer
The PC and the VoIP_Phone were in two different VLANs.
In any case that is what I am trying to achieve, I have an upcoming installation where the clients office is hardwired with a Single network drop per desk, and they just decided that they are going to use VoIP phones. and I need to implement a VoIP VLan and then at the phone split the a VLan for VoIP and another one for DATA.
