the number of subscriber C, terminates dialling with the dialling end character (# in the
default setting), notifies subscriber C of the call to be forwarded and hangs up to
forward the call. If subscriber C does not want to talk to subscriber A, subscriber B
terminates the call with C (9# in the default setting) and returns to the call with A.
