FOP - no activity shown

Hello

I have FreePBX 2.5.1.5, Asterisk 1.6.1.1 & FOP 0.29

I can see online/offline status for extensions & trunks.
I can not see busy/in-use information for extensions & trunks.
In short - all the icons are either green or grayed out.

Please advise what to check. Thanks!

The FOP does not offically support asterisk 1.6.x (or versions past 1.4.22.x. One reason is that the code has not been updated to support the Dadhi devices.
