CUCM - CallBack

     The Cisco Call Back feature allows you to receive call back notification on your IP phone when a called party line becomes available. 

  1. IP phone user A calls IP phone user B in the same cluster. 
  2. If IP phone B is busy or there is no answer, IP phone user A activates the Cisco Call Back features through the CallBack softkey. 
    1. The CallBack softkey can be activated while the call is ringing (RING OUT state). Pressing the CallBack softkey while the call is ringing cancels the call. It does NOT work if the call gets sent to voicemail.
    2. The CallBack softkey can be  activated after the call has ended (ON HOOK state).
    3. The CallBack softkey can be activated during a consultation transfer (CONNECTED TRANSFER state).
  3. IP phone B becomes available. Phone B either went ON HOOK after their call ended. Or they got back to their desk and picked up their phone (OFF HOOK state).
  4. IP phone A receives an audible alert and visual notification that the DN is available. Since Cisco CallManager remembers the dialed number, IP phone user A can then press the Dial softkey to reach IP phone user B.

CallBack Configuration Requirements:
  1. Enable Cisco Extended Functions (CEF) on all servers via Serviceability
  2. Add the "CallBack" softkey to the ON HOOK, RING OUT, and CONNECTED TRANSFER states.
  3. Apply the CallBack softkey templates to the phones.
  4. (Optional) Review and modify the CallBack Service Parameters as needed
  5. Test CallBack!
