How do we get Inter-Tel phones to automatically boot into the voice VLAN on a Cisco Catalyst Switch?
If we put the Inter-Tel 8520 phones on a port with switchport access vlan 2 (the voice vlan), they get the correct IP information from the DHCP server. If we put the phones on a switchport with solely voice vlan 2, it boots into the data vlan instead. I have defined options 66 and 67 in the DHCP server, though I'm not sure correctly.
We need the phones to boot into the correct VLAN automatically in case someone plugs a PC into the phone.
Any ideas??

Works, but can't use PC port for data.
switchport access vlan 2
switchport mode access
switchport voice vlan 2
switchport priority extend trust
srr-queue bandwidth share 10 10 60 20
priority-queue out
mls qos trust cos
auto qos voip trust
spanning-tree portfast
Doesn't boot into VLAN 2:
switchport mode access
switchport voice vlan 2
switchport priority extend trust
srr-queue bandwidth share 10 10 60 20
priority-queue out
mls qos trust cos
auto qos voip trust

The voice vlan command will only work with cisco IP phones. However, I would try changing the interface to a trunk interface (although restrict the interface to only the vlans you need) and set the data vlan as the default vlan.
In order for data AND phone to work, you need to use .1q tagging on at least on of the devices, not just enable the port as an acces port.
Set the phone to tag Vlan 2, and the switch to trunk vlan 2 (tagged) and vlan 1 (untagged)

Are you saying to set the phone to tag on the phone itself? If we manually enter VLAN 2 for voice and VLAN 1 for data in the phones configuration screen, all is fine with the setup. I'd like to just plug and play though. With other phones, I've read that they boot into VLAN 1, receive their DHCP options, then reboot into the proper voice VLAN. I don't see that as an option with these phones.
You shouldn't need to manually set the VLAN tags, as you said you can set this in the DHCP options.
You may need to consult the manual as to what options the phones read in for its VLAN information, as this is vendor specific. For example, Mitel IP handsets use options 128, 130 and 132 to assign VLAN information.
