The system is an Ipecs 100 ver 5.5Fc. Intermittently when a call comes in and the receptionist picks up the handset the call does not connect and sometimes it goes to loudspeaker. Tbe phone used to have a headset connected but this was removed some time ago. The lcd display still shows an icon of a handset with a question mark in the top right hand corner . The handset version is 1.1Db.
Any ideas?
