bbbking, There are a couple of settings you can check in the CSM Data Manager under Call Modeling and at the Extensions themselves in the Data Manager.
Data Manager - Call Modeling
1. Open Data Manager, click Call Modeling in the left hand section.
2. Switch to the Internal Calls tab at the bottom of the window. Make sure both of these check boxes are checked.
For additional Help you can always click the Help link at the bottom of the window (or hit F1 depending where you are) and it should provide a detailed help window for the section/window you are currently looking at, Mitel provides some pretty good help files in most of their systems.
Data Manager - Extensions
1. Open Data Manager, click Extensions in the left hand section.
2. Double click on any extension number to bring up the properties window of the extension.
3. Change to the Internal Calls tab, Enable Check boxes for internal calls arriving at the device or intenal calls made by the device.
As I stated above, if you need additional information on the options available in this screen you should probably reference the Help link, or try the F1 key depending where you are.
I hope this helps you out!
