Question : How do I configure Voice VLAN's for Cisco 2960 switch?

I should preface this by saying I know next to nothing about Switches! This implementation was originally constructed and rolled out by a 3rd Party but since then we have had a switch failure and did not have backups. I was able to get data back up and running with the below config, but its apparentely wrong because my on-site Cisco 7960 phones refuse to pull an ip address. It appears that I may have configured the vlan's improperly. Can anyone take a look and throw out some inputs? Thanks!

Answer : How do I configure Voice VLAN's for Cisco 2960 switch?

Cisco TAC ended up resolving this for me. I neeed to configure trunking on the switch port that interfaced with the router's gigabit ethernet ports. So basically I needed this:

interface FastEthernet0/21
switchport mode trunk
