Hi Saul, the problem is the 3905 telephone in conjunction with the SX300 switch. The 3905 phone has a bug where it won't receive the vlan correctly. To fix this, you need to disable the lldp transmit on the switch

Hi, this bug should be fixed on 9-2-2ES2.

The bug id is CSCub09465

CP-3905  is connected to Cisco Small Business SF300-24P. LLDP-MED is enabled in  the switch port with a network policy advertising the voice VLAN.

CP-3905  fails to learn and change the operational VLAN value from 4095 to the  advertised vlan id. Please see attached packet captures. The phone  advertises its own capabilities and the switch replies back with the  network policy. It seems that CP3905 is not processing it.

After disabling LLDP Tx in the switch port, CP3905 learns the vlan id via CDP
