Thinking of introducing voip in our network. Have Cisco 2960 switch and Cisco Catalyst 500 switches.
Have one of the ip phones with 2 x 10/100 interfaces. Idea being to connect a desktop PC to one of the ports.
The best practice is to set up a voice VLAN and data VLAN.
How should the link between the IP Phones and the Cisco switch be set up? As a Dot1Q Trunk? Is that possible?

this is voice vlan config for 2960 from cisco.com
or
interface FaX/Y
switchport trunk native vlan [datavlan]
switchport trunk allowed vlan [voicevlan],[datavlan]
switchport mode trunk
switchport voice vlan [voicevlan]

Actually I use
switchport mode access [datavlan]
switchport voice vlan [voicevlan]
I prefer this over leaving user ports in trunk mode.

what does the following mean?
from the link above:
Note: Voice VLAN is only supported on access ports and not on trunk ports, even though the configuration is allowed.
