Redial and Call Return

From Pbxnsip Wiki

To redial the last number called, just dial *66.

Call Return (*69) will dial the number of the last call that you missed. The number will be available until you establish a call to that number. This will prevent you from calling back the same person twice.

If you reach an external mailbox the system will believe that the call was established successfully and clear the number. If you reach a mailbox of another extension on your PBX system, the call return number will not be cleared and you will be able to try to reach that extension later by dialing the call return code. The PBX will only store a call return number for calls that contain a valid caller-ID.

Please also note that if you have several telephones that share the same extension number, these devices will share the same redial and call return number.
