External calls
A ringing signal and a flashing lamp indicate an incoming call. If you are connected to a digital trunk line (ISDN), the display shows the number of the external caller and in case of diversion in the public net the display shows the number of the diverted as well as the calling party, see also section “ISDN Facilities” on page 73 (Dialog 4222 Office / Dialog 3212 Standard telephone).
