If this switch is anything similar to the 3500XL, it will allow you to configure the voice VLAN but it isn't going to work. There are some serious limitations with voice and the older hardware.

Is that switch running the latest code for that model should be something like 12.0.5(WC17)? What model phone are you trying to use?
Beyond something like that I really don't know those switches are way beyond EoL and I've never used a phone with them, besides the auto qos commands which is not on those switches, those two port configs you show are the way I have done (fa0/1) or do now do (fa0/2) phone ports.

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
description LAN connection to Winnet Labs Switch
no ip address
duplex auto
speed auto
!
interface FastEthernet0/1.2
encapsulation dot1Q 2
ip address 216.24.19.1 255.255.255.248
no snmp trap link-status
!
interface FastEthernet0/1.7
description Winnet Labs Voice VLAN
encapsulation dot1Q 7
ip address 216.24.19.73 255.255.255.248
no snmp trap link-status
On the switch....
interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
spanning-tree portfast
!
interface FastEthernet0/2
switchport access vlan 2
switchport voice vlan 7
spanning-tree portfast
!
[...]
interface FastEthernet0/9
switchport access vlan 2
switchport voice vlan 7
spanning-tree portfast
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....
