There is nothing special about a voice VLAN. At most it is a VLAN with a QoS rule set on it. It is quite common that switches support a 'voice' VLAN for their own company's VoIP handsets that uses LLDP or similar to make the configuration easier, but that is all it is.
Essentially if you need just a VoIP device on the port, simply set it in access mode and choose the VLAN that is used elsewhere for voice.
If you need a port to be for a PC and a VoIP handset, with the PC plugging into the second LAN port on the handset, create a trunk port and set the PC VLAN as native. The VoIP handset then needs to be set to be on the voice VLAN by tagging it's traffic. This can usually be done manually on the phone, or if you have more than a few via DHCP options. If using DHCP options you will need to put the option to set the phone's VLAN on the scopes for both the intended 'voice' VLAN and the native PC VLAN. The PC will ignore it.
It's actually easier to set up than describe, once you know the DHCP option for your make of VoIP handset.
