The IAQ flag is a parameter which determines whether the ICD Extension field appears on the Users page within CUCM. Generally, this flag is set to false until IPCC has been integrated in which it is then set to true.

For those of you still using versions of CallManager previous to 5.x, or those CCIE Voice candidates studying the V2.0 blueprint, this flag can be located within DC Directory and can easily be changed. You can find steps for doing this HERE (Doc is for Ver. 3.3, but still applies to 4.1.3).

Now, you may be asking yourself, “Why would I manually want or need to flip this flag?” It is no secret the CCIE Voice lab is a time pressured environment and there is A LOT to configure in the allotted 8 hours. So as CCIE Voice candidates, we are always looking for shortcuts or ways to improve our time and save a few minutes here and there. One goal when configuring CallManager on lab day is to minimize the amount of times that you have to go back to a given page and hopefully configure everything on that page the first time around. This is especially true when configuring your devices within Callmanager, but also applies to creating users. If you are in the process of creating your required users but you have yet to integrate IPCC, why not go ahead and flip the IAQ flag, and set the ICD extension for those users so that you can do it all at once and not have to jump back over to CCM to complete this after your integration? Another good reason is for those times when you may finish your IPCC integration and the ICD extension field is still not showing up. This has happened to me on a few occasions.

For those of you currently studying for the new V3.0 Blueprint, you know that DC Directory is no longer being used. So where is this flag located and how do you change it?

This flag is now located within the Informix database and can be changed by following these steps:

1. SSH into your Pub.

2. To view the current status of this flag, from the CLI, run the following command:
run sql select paramname,paramvalue from processconfig where paramname like ‘%IAQInstalled%’

The following will be displayed:
paramname paramvalue
================ ==========
IAQInstalledFlag F

3. To set this flag to true, run the following command:
run sql update processconfig set paramvalue=’T’ where paramname like ”%IAQInstalled%’

4. To confirm that the IAQ Flag is now set to true, run the command in step 2 again.

The following will now be displayed:
paramname paramvalue
================ ==========
IAQInstalledFlag T

Although changing this flag is a little more difficult than it is within DC Directory, it would still be valuable to know how to do this and may just save you a few troubleshooting headaches on Lab day.
