Pressing the REDIAL button again will cancel the transfer operation.
This is the case for local calls as well as for calls received via an analogue trunk line from satellite equipment or with
shore lines connected.
2.3 Receiving calls
When receiving a call, different ringing signal types will give the called party some information about the origin of the call.
The following ringing signals are implemented:
Ringing signal Description
2 short rings and 5sec pause Local call
1sec ring and 5sec pause Incoming call from a trunk line
3 short rings and 5sec pause TalkBack call
2.4 Priority calls
The priority call function is used when a user wants to interrupt an ongoing call (for an important message).
Priority calls are made by first dialing the priority system call number, which by default is set to * (asterisk). When the
priority system call number is dialed, a new dial tone will be heard. Proceed by dialing the number of the extension you
wish to interrupt (e.g. 20).
The priority call facility will place the other party involved in the interrupted call on hold. When the priority caller hangs up,
the interrupted conversation will be re-established.
2.5 Outgoing cals (via external long-distance telephony device)
Outgoing calls (e.g. via satellite or shore lines) are made by first dialing the call of trunk line connected to the
communication equipment to be used. The trunk line is the direct link to an external long-distance telephony device. This
can be an Iridium satellite terminal, a fleet broadband satellite terminal, or a VoIP box making IP calls possible.
Trunk lines have a default system call number 00.
If the trunk is free, then the connection to the external communication equipment is established.
The dialing instructions applicable to the external communications equipment must then be used. For example, some of
them instruct dialing to be terminated by the # key. Or the call can only be established by dialing some kind of payment
service first. These details must be known by the user of a trunk line.
2.6 Outgoing calls via the CDM system
When outgoing calls are logged and controlled by the CDM system, such a call is dialed in the following way:
Dial the number of the Call Data Management (CDM) system, which by default is #10. A new dial tone will be heard. Dial
your personal account number (default: 2 digits) followed by your personal PIN code (default: 4 digits).
If this is the very first call using the system, the 4 digits that are entered will be stored by the system as your personal
PIN code. These digits are not accessible, and the only way to change the PIN code is for the system administrator to
reset the PIN code.
The account number and PIN code will be checked against the user database. If the account and PIN code are valid,
the call is automatically transferred to a trunk line. If the trunk is not busy, the connection to the external communication
equipment is established. The dial tone of the external equipment will be heard and the dialing instructions applicable to
that equipment must be used.
When your call is terminated, a call data record will be logged in the call database.
Note this requires CDM to be installed on the system.
