Do not use voice vlan, try configuring the port only with the VLAN 2, if the IP Phone get the correct IP address, may be there's a problem with the voice vlan configuration.

Thx

Did you make a "factory reset", to clean all configs on the phone?

Is this a 3560 switch? I have seen this behavior several times and have yet to find a solution, the most stressing issue is you put another phone( 7960/40 etc) on that port and it works.

Do a  show vlan and make sure vlan 2 exists.

Do you have CDP enabled on the switch?  Cisco phones use CDP voice vlan functionality.

I'm having the worst time trying to figure out a problem.

The issue is that a 7912 phone seems to be getting an IP address in the data subnet.  We've tried two configurations on the switchport level and neither are working...

Interface fa0/1
switchport mode access
switchport voice vlan 2
srr-queue bandwidth share 10 10 60 20
priority-queue out
mls qos trust cos
auto qos voip trust
spanning-tree portfast

AND/OR

Interface fa0/1
Switchport mode trunk
switchport trunk encapsulation dot1q
switchport voice vlan 2
srr-queue bandwidth share 10 10 60 20
priority-queue out
mls qos trust cos
auto qos voip trust
spanning-tree portfast

And yet the phone keeps receiving an IP address in the data subnet.

We've verified the following:
- helper-address on the router
- correct DHCP scope
