Hello everyone! I am the IT manager of my company and among other things I manage a PBX Samsung SRV7400 . This PBX has never given problems and in recent years has always done his duty . A few days ago a strange thing is happening. All and only VOIP phones are locked and can not receive or make phone calls to both internal and external. I accessed the system and the switchboard at the meeting Alarms History I found these errors: SVMI RESTART - MGI NTWK REC - MGI RESTART - PRI RESTART - SVMI DOWN - These LOG tell you something ? thank you all
