[cisco-voip] VOICE VLAN with 3500XL

[Syed Khalid Ali]

I trying to configure Voice VLAN with 3548 XL switch. Using the
explanation at the following link:
http://www.ciscopress.com/articles/article.asp?p=98122&seqNum=3 and
http://markmail.org/message/5rd5wgcakkrbkzhc?q=configure+voice+vlan+on+3500xl&page=1&refer=3hhuwgfvz4usf66n

the configuration went fine and phones started to register with CCM.
however, the interface VLAN for voice never is not in "UP and UP"
state.

Is this the default behavior? or something is still missing.
This is what I did:
interface fa0/1
switchport trunk encapsulation dot1q
switchport trunk native vlan 100
switchport mode trunk
switchport access vlan 100
switchport voice vlan 110

The same config follow up to port 23.
Port-24 is connected to router as 802.1Q trunk. this is router on a
stick topology.
