I am trying to connect a cisco router 2650XM with CME to a cat4006 sup II and a L3 card with 7940 phones. Does anyone know what is the best way to configure the Cat4006 for voice? is there a good document that explains how to connect the router (trunk?) to the cat4006 and voice vlans?
Thanks

I can't get to those links. Could you please email me the docs?
Thanks

Since the switch has L3 in it, your default gateway for PC and phone should be terminated at the 4006. (from a good design standpoint).
The switch ports can be configured as trunk or access ports.
Scenario 1: Switch port as Trunk ports
int fa 0/1
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan 4 <---data vlan
switchport trunk allowed vlan 4,5 <---optional
switchport priority cos extend 0 <-- check syntax of this command.
switchport voice vlan 5
OR
Scenario 2: Switch port as Access port
int fa0/1
switchport mode access
switchport access vlan 4 <---Data vlan
switchport voice vlan 5 <----Voice vlan
switchport priority cos extend 0
Scenario 2 will let you plug a PC directly to the switch port. Scenario 1 will not let you do this. You will have to plug the PC to the back of the Phone and the Phone directly to the switch.
In addition to the above, you might also want to turn on DHCP either on the 2651 or the L3 blade itself. The port on the switch to which the 2651 is connected can be configured as an access port in Vlan 5 (Voice). On the L3 blade, you will also have to configure Vlan interface as follows.
int vlan 4
description Data vlan
ip add
int vlan 5
description Voice vlan
ip add
Again my assumption was that you have IOS on your 4006..If its CatOS then your configurations will change as follows:
set vlan 4 2/1
set port auxiliaryvlan 2/1 5
set trunk 2/1 auto negotiate 4,5
Hope that helps@!

We are running catOs 5.5.4 or so and Version 12.0(7)W5(15b) on the L3 router blade. Is there a good version of both cat Os for the switch and IOS for the router blade I should upgrade to before attempting to make it work?
Also on the vlan configuration the L3 blade is confugured with Port Channels: example
How would you link the port-channels to the aux vlan?
