Cisco IP Phone: What Does The Circle With A Dot In The Middle Mean

Honestly, I have no idea what that circle with a dot means.  But, here is what I do know.  The port on the switch was not configured correctly for the voice vlan.  I sent out another engineer, and he moved that patch cable to another port that was configured with the voice vlan, and the phone came up at that point.  Chalk this one up to improper configuration of the voice vlan.
