專利商品特色:
The present invention provides a “Phone Log” in a telephone switchboard for recording the extension numbers, the phone numbers dialed by the extension numbers and the accumulated times. When there is an outside call, the telephone switchboard will first check the “Phone Log” whether the telephone number of the outside call is on the “Phone Log” or not; if the telephone number of the outside call is on the “Phone Log”, then the outside call (callback) is connected directly to the corresponding extension; otherwise the outside call will be connected to an auto-attendant for connecting. As the accumulated time of each of the records reaches a time limit, the related record will be cleared out. After the callback is picked up by the corresponding extension successfully, the related record is also cleared out.

專利商品技術說明:
1. A method of telephone switchboard, wherein a “Phone Log” is added in the telephone switchboard for recording extension numbers that have dialed an outside telephone number, telephone numbers dialed by the extension numbers, and accumulated times, comprising the steps of:
a. the telephone switchboard operates to check if there is any outside call, wherein if there is no outside call, the telephone switchboard goes back to check again, otherwise the telephone switchboard checks the “Phone Log” to see if a telephone number of the outside call is on the “Phone Log”;
b. if the telephone number of the outside call is on the “Phone Log”, then the telephone switchboard treats the outside call as a callback, and then connects the callback to a corresponding extension and waits for picking up of the corresponding extension; wherein if the corresponding extension picks up the callback, then communication begins; and if the corresponding extension does not pick up the callback, then the telephone switchboard transfers the callback to an auto-attendant, and the auto-attendant then operates to handle connecting;
c. in step a, if there is no record of the telephone number of the outside call on the “Phone Log”, then the telephone switchboard transfers the outside call to the auto-attendant, and the auto-attendant then operates to handle connecting wherein when an original caller uses the corresponding extension for dialing an outside telephone number through the telephone switchboard, the callback is directly connected to the corresponding extension even though the outside telephone number did not accept the call from the corresponding extension and did not know the extension number of the original caller.
2. The method of telephone switchboard for connecting directly a callback to an extension of an original caller according to claim 1, wherein a record on the “Phone Log” of the telephone switchboard is cleared out after a corresponding accumulated time reaches a time limit.
3. The method of telephone switchboard for connecting directly a callback to an extension of an original caller according to claim 1, wherein after the callback is picked up by the corresponding extension successfully, the related record is cleared out.
4. The method of telephone switchboard for connecting directly a callback to an extension of an original caller according to claim 1, wherein the telephone switchboard is a conventional telephone switchboard or an internet telephone switchboard.
