Initiating External Callback on Busy
If you have initiated a callback, as soon as the other subscriber has
hung up the receiver to end the call, the public exchange calls you. If
you then pick up the receiver, the other subscriber will be called. If the
other subscriber picks up the receiver, the connection for the call will be
established. This deletes the callback procedure in the public exchange.
Requirements:
• Fulfilling the technical requirements for a callback on busy (for
instance, not all network providers provide callback on a PTP
connection)
• Service feature CCBS (callback on busy) is enabled by the network
provider.
Important: On system phones, this function is called via the menu/
phone app (optional, see manual for the phone).
Note: To use this function at ISDN phones or to delete it again, this
function must be supported via a function key or via the menu by the
respective phone (optional, see manual for the phone).
Note: You can also use this function on analogue phones, where it can
be performed via the T-Net function key/menu (optional, see manual for
the phone). Instead of the announcement by the public exchange, you will
hear the confirmation tone.
If the connection you are calling is busy, proceed as follows:
1. Press the Flash key or the Query key .
2. Dial *37#.
