I just upgraded a UCM cluster from 6.1.2 to 7.1.2. AC is heavily used in this environment.
A regular procedure for an AC operator was to ad-hoc conference a parked call with an active call. In 6.1.2, an AC operator could have an active call, press conference, enter park number, press conference again, and the three of them were in a conference.
After the upgrade to 7.1.2, the AC operator will conference the active call with the parked call, press conference a second time, and it AC will bring up the dial window again. This leaves AC with a call in progress and the previous parked call on hold.
I'm assuming that the functionality has changed between releases. Currently, the AC operator is having to use the conf soft-key on the physical phone to make this work.
I think that join would be a better workaround, but join and direct transfer are grayed out in AC.
The question is, does anyone know of a way to conference with a parked call in 7.1.2, or make the join function work in AC?
