Hi, I have 5 T19P phone with Firmware version 31.72.0.76.
I receive about 10 ghost call each hours. They are not loggued into the pbx. I also desactivated the Allow IP Call. I see many option like Acception SIP trust only server but I don't have it in my phone. Help !!!
First, do I have the latest firmware version?
Second, What I need to do?
Thx
