Display of the Registration Status
If the display of the registration status is switched on, the individual registration status of the subscribers will be signalled via the LEDs of the speed dialling keys assigned to internal VoIP subscribers. If the corresponding VoIP subscriber is not registered at the PBX, its LED will blink yellow.
 
Proceed as follows:
Using COMfortel Set (page Settings/functions > signalling/ringer, check box Registration status subscriber)
Using the telephone (function key or menu settings > signalling > reg.status scr.)
