[cisco-voip] ITL Files and UC Upgrades

Wed Jan 15 15:05:05 EST 2014

Thanks Ryan. I was wondering about setting the rollback parameter on the v9 cluster before registering phones to it, and then reverting it back to normal once I was convinced everything was working fine. 

Is this what you were trying to communicate?

Not to take away from the work that Stephen and company do at UnifiedFX but TAC has tools that work via signaling (requires registered phones) and directly access the phone's web server (requires working authentication URL). Between the two of them it should cover all but the most difficult of cases. 

For bringing up a new cluster and migrating if you are concerned about moving phones back and forth then you may just want to set the rollback parameter on the new cluster before you even enable the ccm service. You'll need to make a tweak to the corporate directory service for it to work (check out CSCuh96737 for more details). 

Whatever route you choose definitely check out PhoneView, it's a great app and does way more than just ITL stuff.

That is true. 
We hadn't restricted web access etc on v7 so it wasn't an issue for me at the time. 
We had approx 1000 handsets that had an issue county wide in the UK. So trying to manage that in a timely fashion was a very big issue and at the time we faced having to try and track down them individually. 
So this tool saved us a significant amount of time.

Andy, 

The issue with the tool is that it requires settings access and web access to already have been enabled on the phones prior to the outage. Also, there’s usually many other ways to resolve ITL issues rather than deleting the ITLs from all the phones in the cluster.

If you get into problems with rolling back TAC have a tool they will send you which will erase ITL config on a handset list. 
I have had to use this in the past with good results.

Thanks, I'd definitely have to consider that. What I would do, is make sure to see what the factory loads are first, and if they are not our default loads, re-install the default loads to update those xml files accordingly. Or at least that's what I gathered I can do. Reinstalling an existing file should be fine.

A factory reset removes the ITL, but could also put you on a firmware that is not a direct jump to your current Device Defaults, leaving the user stuck on the older load.

hi Brian, 

I'm planning a v7 to v9 upgrade and will be looking at (and testing) back out procedures. My hope is that if we need to roll back to v7, using the roll back parameter will help, but in the event it doesn't we'll have to manually fix things. The document you reference talks about deleting the ITL files manually, but I'm wondering if performing a factory reset does the same thing? 

My concern is that the instructions to delete the ITL file are (might be) a little more complicated than a factory reset. 

Thoughts?

Dana, 

The rollback option requires all phones to be reset after changing the Enterprise Parameter so that the phones can get the new blank ITL. After they get the new blank ITL is when you can then move it to the other cluster. The rollback option isn’t preferred since phones on the old cluster will have problems with secure services such as corporate directory before they are moved to the new cluster. I’d suggest using the Bulk Certificate Export/Consolidate/Import option to maintain 100% functionality while also allowing you to roll phones back to the old cluster if something went wrong with the upgrade easily. Check out https://supportforums.cisco.com/docs/DOC-15799 for more info on this.

Hi all, 

I was just testing the process for migrating handsets from an old 8.0 cluster on MCS hardware to new virtualised UCM. 

· I set the Enterprise Parameter – Prepare cluster for rollback to pre 8.0. 
· Restarted the Trust Verification Service on all nodes. 
· Restarted the TFTP service on all nodes. 
· Restarted my pilot handset. 

· Once this was completed I changed the TFTP servers to point to the new cluster and restarted the phone. 
· The phone came back on the old cluster. 

I had to manually go in to the phone and delete the ITL file and reset it again before it would register to the new cluster. 

Am I doing something wrong? What is the correct procedure? (I am aware of other third-party applications which will do this for me). 

Cheers 
Dana
