Tones
The PBX supports different tones on the receiver in order to signal the various operating states on the PBX:
External dial tone (long dial tone): After dialling the exchange line access number, when a free external line is available – dialling a phone number is possible
Internal dial tone (extension dial tone): After picking up the receiver or after pressing the Flash or Query key, when a free line is available – dialling a phone number is possible
* Note: On standard VoIP phones, a dial tone is generated by the phone itself, even when no free line is available.
Confirmation tone: At the completion of programming, when the programming has been successfully executed
Busy tone:
After picking up the receiver, when no free line is available or an authorisation is missing
After dialling a phone number, when the desired connection is busy or the network is overloaded or an authorisation is missing
At end of call
During programming, when the programming was unsuccessful or an authorisation is missing
During a Call Through call, when the phone number transferred from the mobile phone is not permitted to use Call Through
Call tone: during the call phase
Special tone 1 and special tone 2:
After picking up the receiver (when a special tone has been configured as notification that call forwarding, do-no-disturb or baby call has been switched on)
After picking up the receiver (when a special dial tone has been enabled), when the call data memory is full
Call waiting tone: During a call (when call waiting has been enabled), when another call comes in – it is possible to accept or reject the additional call
