internal numbers ID masking

This is something I wish was easier to do with callmanager. Here is what we do..

-Make a new partition, we call it MaskCLIDAs<number&gt;
-Make a new Calling search space, we call it Device_MaskAs<number>
-Put the MaskCLIDAs<Number&gt; partition as the first entry in the new CSS, and then put any additional partitions you would need to call (outbound partitions etc)
-Make a Translation pattern that will match all your internal extensions, and use it to modify the calling party number to whatever you like. Make sure you set the new calling search space as something that can call your internal numbers. The new translation pattern should be in your new partition.
-Configure the phone with the new CSS

basically you want interal callers to hit that new translation pattern when they call another internal number, so that it modifies the calling party number and then proceeds as normal with the call. Otherwise it places outside calls as normal.

Does that help? As you can imagine if you do this alot, you get alot of partition/CSS/translation pattern clutter on callmanager.

One thing to be careful of is to make sure your masked phones can still call everything they need to (call pickup groups tripped us up on this) with the new CSS. And also make sure they still cannot call things they shouldnt
