Verifying the configuration
Operation 1: When the subscriber at Telephone C dials 1000 to call Telephone A that is in a
conversation with Telephone B, the subscriber at Telephone C hears ringback tones, and the subscriber
at Telephone A hears call waiting tones. If then the subscriber at Telephone A hangs up, Telephone A
rings, 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 that is in a
conversation with Telephone B, the subscriber at Telephone A can press the flash hook to start a
conversation with Telephone C, and 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.
Call forwarding configuration example
Network requirements
As shown in Figure 44 , configure call forwarding on Router B so when a user places a call from
Telephone A to Telephone B, Router B forwards the call to Telephone C when Telephone B is busy, and
Telephone A and Telephone C start a conversation.
