[cisco-voip] Phones not registering with 2960S switch.

Phone un-registers when I type "switchport access vlan 205"  I have both 7965s and non-Cisco devices I need on vlan 205.  I see nothing wrong with this setup.  Phone uses CDPv2 to get the voice vlan not "Switchport access vlan x".



Phone load is SCCP45.9-2-3S
