If it is a Cisco switch you do not need a trunk configuration.
When you enable voice vlan, a special-case 802.1Q trunk automatically is enabled through a CDP information exchange between the switch and the IP Phone. The trunk contains only two VLANs a voice VLAN (tagged VVID) and the data VLAN. The switch port's access VLAN is used as the data VLAN that carries packets to and from a PC that is connected to the phone's PC port.
If an IP Phone is removed and a PC is connected to the same switch port, the PC still will be capable of operating because the data VLAN still will appear as the access VLANeven though the special trunk no longer is enabled.
The trunk configuration is required though if a Avaya IP phone is conencted to the Cisco switch.
