Operation 1: When the subscriber at Telephone C dials 1000 to call Telephone A which is already
engaged in a call with Telephone B, the subscriber at Telephone C will hear ringback tones. At the same
time, the subscriber at Telephone A will hear call waiting tones, as a reminder that a call is waiting on
the line. If then the subscriber at Telephone A hangs up, the telephone will ring, and the subscriber at
Telephone A can pick up the phone to start a conversation with Telephone C.
Operation 2: When the subscriber at Telephone C dials 1000 to call Telephone A who is already
engaged in a call with Telephone B, the subscriber at Telephone A can press the flash hook to start a
conversation with Telephone C, and thus Telephone B is held. The subscriber at Telephone A can press
the flash hook again to continue the talk with Telephone B, and then Telephone C is held. Note that, in
this case, the call hold function must be enabled on the voice subscriber line connecting to Telephone A.

Network requirements
As shown in Figure 72, place a call from Telephone A to Telephone B. Router B forwards the call to
Telephone C when Telephone B is busy. Finally, Telephone A and Telephone C start a conversation.
