Problems solved by technology

There are the following problems in this way: 1, the user needs to inform all friends (including its customers) who had contact with it before the new number
In this way, the communication fee for transferring the incoming call of the user's home number to the VoIP phone number is the domestic long-distance communication fee, which is generally higher
[0009] 2. This solution can only reduce the cost of receiving calls in the roaming area, and it will not help the high cost of making calls to other areas other than the roaming area.

Embodiment 1

[0045] figure 1 Shown, a kind of specific embodiment of the present invention is, a kind of telephone agent equipment based on VoIP technology, comprises:

[0046] Telephone module: under the control of the control module, transfer information between the telephone network and the control module;

[0047] VoIP client module: controlled by the control module, transfers information between the control module and the VoIP server;

[0048] Control module: control the telephone module and VoIP client module to complete the establishment, maintenance and release of communication links, and transfer information between the telephone module and VoIP client module.

[0049] This example uses the above-mentioned method for receiving a call in a roaming area, including the following steps:

[0050] The proxy device user described in A.1 registers his roaming phone number on the control module, and at the same time configures his home phone number on the phone module.

[0051] The main...

Embodiment 2

[0061] The equipment in this example is exactly the same as that in Example 1. The specific steps of the method for making an international call domestically using this equipment in this example are:

[0062] The agent device user described in B.1 registers his primary phone number on the control module and sets verification information, and then configures the secondary phone number on the phone module.

[0063] The primary phone number refers to the local phone number that users often use when roaming abroad.

[0064] The secondary phone number is the user's domestic phone number. This number is mainly used to make calls in roaming areas. In China, users do not (or seldom) communicate with the outside world through this number, that is, this number is rarely known to the outside world.

[0065] B.2 The proxy device user uses any phone number as the calling number to call the secondary phone number.

[0066] When the calling number calls the secondary telephone number, any ...

Abstract

The invention discloses a telephone agent device based on a voice over internet protocol (VoIP) technology and a call making and answering method by a telephone agent device. The telephone agent device comprises a telephone module, a VoIP client module and a control module, wherein the telephone module is controlled by the control module and is used for transferring information between a telephone network and the control module; the VoIP client module is controlled by the control module and is used for transferring the information between the control module and a VoIP server; and the control module is used for controlling the telephone module and the VoIP client module to finish the setup, the maintenance and the release of a communication link and transferring the information between thetelephone module and the VoIP client module. The telephone agent device has the advantages of simple structure and low acquisition cost, and is easy in implementation. The invention also discloses two call answering methods for dialing an international call interiorly and an international roaming call for users by means of the telephone agent device, and the communication cost generated by the methods is equivalent to the local communication cost.

Description

technical field [0001] The invention relates to a telephone proxy device based on VoIP technology and a method for using the device to make and receive calls. Background technique [0002] Business people need to frequently travel between major cities in China or between domestic and foreign countries. During this process, they need to maintain communication with the outside world anytime and anywhere. In mobile communication, when the place where the user communicates is beyond the coverage of his home location register (HLR), the communication at this time is called roaming communication. Roaming can be divided into domestic roaming and international roaming according to region, and can be divided into intranet roaming and internet roaming according to the network used for communication. Currently, the main communication methods used by mobile users during roaming include voice communication, short message and email. Because of the best real-time voice communication, it ...
