A call made by another internal subscriber is disconnected and then connected to a separate
telephone. This function is useful, for example, when using answering machines.
Call Through
This function also enables, e.g., field representatives to use the least cost routing function and
VoIP/GSM routing on the PBX. To prevent high costs when using mobile telephones, an inter-
national call be made by first calling the PBX and then connecting to the desired connection
from the PBX. The Call Through function also enables the direct redial of any telephone
number.

If you are already in a call, the call waiting function notifies you using the call waiting tone when
another communication partner is calling.

After initiating a callback on no reply (CCNR), a subscriber is automatically called back by the
PBX or by the central office when a subscriber is reachable again.
