I made the suggested changes, but still no service on the phone, and the switch does not show vlan7 as associated with any ports in "show vlan". How should a voice vlan show up in "show vlan"? Should I even be expecting it to be associated with ports?
On the switch now...

OH, on the 2900xl, you may need to do this:
Switchport trunk native <datavlan>
Then, your switchport voice as-is.

Trying to set up 2 VLAN's to run on a switch, one for access, one for voice. The access VLAN works fine, but the voice VLAN just does not seem to be associated with any port as far as the switch is concerned. The switch is a 2900xl.
On the router....
interface FastEthernet0/1

interface FastEthernet0/1.2

Plugging a netbook into port 2 works on VLAN2.
Plugging the netbook into the PC port of VOIP phone which has the PC port configured to VLAN2 works, then plugging the phone into port 9, allows the netbook to work. Changing the access vlan to 7 when the phone itself is configured to be VLAN 7 causes port 9 to show up associated with VLAN 7, and then you can make calls with the phone. But with the voice vlan set to 7 and the phone VLAN ID set to 7, vlan 7 does not show up as associated with any ports at all and the phone just does not work....
