The Completion of Calls on No Reply (CCNR) creates a callback in case a person cannot be reached
(e.g. the person is not on its desk or busy) at the moment.
To use this function, the CCNR function has to be enabled in the administration portal
and in the phone extension. Click on the CCNR check box under Administration / Profile
to activate the function.
Generating Callbacks
A caller generates automatic connection establishment within the private branch exchange (PBX) to
a previously busy party (only internally). If the the other party cannot be reached, the caller is able
to use the callback function. In order to activate the function, insert *5 into your key pad. An
accoustic confirmation will finalize the activation. As soon as the other party is available again, its
end device receives a callback generated by the PBX. As soon as the other party answers the
callback, the PBX sends out a call to the initial caller and establishes the connection.
Erase Callbacks
If the callback is no longer needed, all call backs can be erased by entering the **5 code into the key
pad. An accoustic confirmation finalizes the erase.
An overview of all function codes of the PBX can be found here.
