Hi
I have a cius registred on CUCM 7.1.5 20000 -6 with device pack 7.1.5.34074-1, the phone can make and receive calls but i can't hear anything in the handsets (and speaker), even not the dial tone.
Cius is connected to a UC500 (just to have PoE, i don't have a PoE switch) to power docking station.
