I am using CME/CUCME 12 and 8861 phones with 12.6.1. The blf functionality works for a while, and then stops working. Lights are off when a line is in use, and on others sometimes don't go out after someone hangs up the call. Rebooting the phones or re-registering them gets them working properly for a while, but then they start acting weird again.
I'm going to upgrade phone software and see if that helps, but how I can debug the presence service on the router?
thank you!
