Console Version: 1.4 (1ES5) was in version 4.1.3 SR1 the Engineering Special 25 and under, I believe.
Server Version : 1.4 (1ES9) is in version 4.1.3 SR2, and is in Engineering Specials 25 and above.
It looks to me like your consultant did not upgrade the Attendant Console machines, other wise your Console version and Server version would match; they would look like this:
Console Version: 1.4 (1ES9)
Server Version : 1.4 (1ES9)
ES9 is the latest version contained in SR2; I just did the SR2 update last week, and updated all our Attendant Console versions to ES9. ES5 was the version that was in SR1 for 4.1.3, I believe.
Upgrading the Attendant Consoles is very easy. Do exactly what I suggested in my previous post - Go to Help menu, and click "About Cisco CallManager Attendant Console." There should be an Upgrade button right below the Console and Server versions (if the versions matched, there would be no Upgrade button). To upgrade, just click the upgrade button. A message will appear that says the old version must be uninstalled before the new version is applied - just click OK. It will automatically uninstall the old version and install the new version for you. When it's finished, manually open up the Attendant Console program and make sure your Call Control comes up and your line status is working (just two things I always do when I upgrade our Attendant Consoles), and place a test call to and from the Console. And that's it - you're done. The process is pretty painless.
As a side note, every time major updates are performed on the CallManager software, there's usually a new version of Attendant Console, BAT, CAR, etc. You can check the release notes for the upgrade/update and see what versions are being installed, and compare them to what you actually have, to see if any of them needs to be upgraded after the CCM software upgrade/update.
Now, if after you update the Attendant Consoles you're still having the same issue, I would check the CallManager Event Logs and see if you're seeing failover/failback messages (things like Transient Connection Attempt errors for the phones attached to your Attendant Consoles). If you're having a network issue/connection issue with your phones on the Consoles, updating the Attendant Consoles isn't going to help that. But, it's always a good idea to update all applications after you do an upgrade/update.
