I've recently began working for a VoIP Provider and I am constantly seeing VoIP Phones pulling different VLANs than the Host that is connected to it i.e. daisy-chained.

When I've tried to look more into this the only method I can find is to set the VLAN Tag in the phone itself as otherwise I don't see why both wouldn't get whatever Tag is set on the Switch Port.

Is there another way to accomplish this? I understand the usefulness of the setup, I'm just not sure how it's being done and haven't been able to find anything that doesn't involve the phone itself.
