Preferred method for Obihai devices to Detect the proper VLAN

[munozj]

What's the preferred method for having ObiHai devices auto detect the voice VLAN on our network.  I have that VLAN tagged on most of our office jacks but the PC VLAN is the untagged network.  I'd like users to be able to plug in their brand new phones to these jacks and have the phone detect the proper VLAN, connect up to the proper network leaving the PC port of the phone untagged.
