We have a situation where voice vlan is vlan 2 at a client's site. We want to insert a UC540 into the network and keep the same VLAN 2 for voice - from CCA 2.2.5 it doesn't appear to be an option.
please advise
Thanks

Yes you can.
I just tried this on a UC540 in CCA 2.2.6 and successfully change the Voice VLAN from 100 to 2. Although I was doing this in 2.2.6, this should work the same in 2.2.5. (Note: that this WILL cause disruption in your network, so do this during down time.) Make sure you're plugged directly into your UC540.
I'll post a Lab with screenshots on this later, but for now I'll give you the short of it:
Note: If you have an ESW expansion switch installed, the new Voice VLAN information will be configured for you automatically, and all phones attached will also reset, and re-register)
Your UC540 is now configured on your new Voice VLAN.

The problem is this will not change is the IP source address under telephony-service.

Adam,
In the example provided above, the ip source-address remains unchanged. (10.1.1.1 port 2000) I believe the aim was to change the default Voice VLAN ID, and not the ip scheme? I suppose this would make sense if Pat was conforming to an existing voice subnet. However, even If this was the case, the voice subnet and ip source-address can still be defined during the Telephony Setup Wizard.

Unfortunately, this is not a change you can make with CCA 2.2.5. You would have to use custom CLI configuration to accomodate this.

I don't see this as an issue in 2.2.5, so go ahead and give it a shot?
If not, 2.2.6 is targeted to be released in a week or two as a maintenance release to 2.2.5.
(bug fixes, and apparently some additional features)

Thanks for the suggestions, will try the configuration after the wizard.
I just thought the CCA wouldn't pigeon hole me to DATA VLAN 1 , CISCO-VOICE VLAN 100. Custom configuration should be whatever i want. Hopefully this gets addressed in CCA 3.0, but will try with current release.
