First, I have a cell phone in a ring group with other extensions. I use confirmation when a call goes to the cell phone. Since upgrade from 2.3.1.2 to 2.4.0 Beta 2.0, the cell phone no longer receives caller-id from the originating caller. It comes in blank or anonymous to the cell phone.
Secondly, the PBDirectory module shows “BROKEN” in the modules list now.
I’ll keep testing and update with other findings as they arise.
