[cisco-voip] Need Help Configuring Cat2924XL

The ports with the voice vlan command need to be in trunking mode. The
switch in the IP Phone is looking for a trunk.

Int fa0/5
 Switchport voice vlan 100
 Switchport mode trunk
 Spanning-tree portfast

Does the 2924xl support voice vlans though? I wasn't aware that it did.

I've got a Cat2924XL with the following relevant config snippets:

rwc-2924xl-131#show vlan
12   DMZ                              active
100  IP Phones                        active    Fa0/7

interface FastEthernet0/5
  switchport voice vlan 100
  spanning-tree portfast
!
interface FastEthernet0/6
  switchport access vlan 2
  switchport voice vlan 100
!
interface FastEthernet0/7
  switchport access vlan 100
  spanning-tree portfast

interface FastEthernet0/24
  switchport trunk encapsulation dot1q
  switchport mode trunk

interface VLAN2
  ip address 172.16.0.131 255.255.0.0
  no ip directed-broadcast
  no ip route-cache


So...  FE0/7 works fine (as you would expect), but neither 0/5 or 0/6 
work ...  The phone sees the operational VLAN 100, but never gets an 
IP..  What the heck am I doing wrong?  Cisco's docs only show the 
"switchport voice vlan" option as being relevant.  Is there something 
I'm missing on the switch config?  I've rebooted the phones and switch a 
few times.

Thanks for any help,
