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.
If the callback is no longer needed, all call backs can be erased by entering the **5 code into the key pad. An acoustic confirmation finalises the erase.
