When dialling out from the analogue phone connected to the Deskmaster 520, it will use the ISDN type
‘3.1 k telephony’ to indicate the call is coming from an analogue extension. If you call up another ISDN
equipment, you can only get connection if the other end accepts this type of call. If you connect fax or
