One of my Mitel 5312 handsets is not recording missed calls etc... the button is showing as configured for call history but when pressed it just displays 0 missed? I have removed and re-added the feature to this.
The phone had issues recently relating to network drop outs, it turned out to be the phone itself i swapped it over with a spare then on the management system just swapped the 2 MAC addresses over so the user kept the same number. Could this have cause any symptoms like this? the other 3 feature keys work fine for call forward, pickup and headset though.
