Call Through
With Call Through, calls are passed through the PBX. This is used, when you do not want to reach a client via the private smartphone but via the company number. The smartphone calls the PBX and gets connected to the desired connection. Call Through allows the direct redial of any phone number.
This way, the called person does not receive the mobile number but the company number.
The phone number to be transferred is configured in the exchange line routing outgoing and is assigned to the according exchange line routing rule set of the Call Through function. Using the CLIP no screening function (availability on the account provided) allows a free assignment of the phone number to be transferred independently from the used connection.
