Embodiment

[0030] This example takes the IP voice gateway as an example, and its method flow chart is as follows figure 1 .

[0031] Firstly, the system records the relevant information of the external calls made by each extension and stores them in the call information record. The recording process is that when the user uses an extension to dial an external phone number, the system judges whether the outgoing call is connected, and if so, records it. The relevant information of this external call is stored in the call information record. If not, no operation is performed. Among them, the relevant information of the external call includes the external telephone number, the calling extension number and the time when the call was initiated. Then when there is an external call When dialing into the host, the system searches the call information record according to the dialed-in outside phone number, and judges whether there is any relevant information about the outside phone in the call inf...

Abstract

The present invention provides an automatic dial-back method and system, which relates to a relay IP voice technique. The present invention solves the problem that the opposite part can not dial back when a user gets an outside line with an extension. The technical proposal comprises the following steps: first, the system records information related to outside calls dialled by all extensions and stores the information in calling information records; then, the system retrieves the calling information records according to outside call numbers dialled in, and judges whether the information related to the outside calls exists in the calling information records or not; if the information is not available, enter a normal calling process and end the current dial-back process; otherwise, prompt outside call users to select the extension numbers recorded; whether the outside call users select the extension numbers recorded or not is further judged; if the outside call users select the extension numbers recorded, the system automatically dials and connects the recorded extension numbers selected by the outside call users and ends the current dial-back process; otherwise, enter the normal calling process. The present invention is convenient for users, and suitable for IP voice gates or group telephones.

Description

technical field [0001] The invention relates to the relay IP voice technology, in particular to the technology of calling back the IP voice extension phone of the relay. Background technique [0002] Currently, when using the IP voice gateway, the E1 interface of the Private Automatic Branch eXchange (PABX for short) or the foreign exchange office interface (Foreign Exchange Ofrice, FXO for short) as a trunk, extension numbers can be assigned to different internal users, but After an internal user dials an external number, generally only the switchboard number is displayed in the caller ID of the called party. Taking the IP voice gateway as an example, when dialing a PSTN (Public Switched Telephone Network) call from the IP network, the caller ID of the PSTN called party can only display the switchboard number, but cannot display the extension number, and the called party records according to the caller ID When calling back a missed call or a received call, the switchboard ...
