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

[0061] figure 1 Shown, a kind of specific embodiment of the present invention is, a kind of telephone agent device based on VoIP technology, comprises:

[0062] Telephone module: under the control of the control module, transfer information between the telephone network and the control module;

[0063] VoIP client module 1 and VoIP client module 2: controlled by the control module, transfer information between the control module and the VoIP server;

[0064] Control module: control the telephone module and VoIP client module one and VoIP client module two, to complete the establishment, maintenance and release of communication links, and between the telephone module and VoIP client module one and between VoIP client module one and VoIP client module one The VoIP client module transfers information between two modules.

[0065] In this example, the method for using the above-mentioned device to make and receive calls includes the following steps:

[0066] The agent device us...

Embodiment 2

[0083] The device of this example is exactly the same as the device of embodiment 1, and the method for using the device to make a call in this example is different from that of embodiment 1. The specific steps of the method for using the device to make a call in this example are:

[0084] 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 template.

[0085] B.2 The agent device user uses any telephone number as the calling number to call the secondary telephone number.

[0086] B.3 The telephone module receives a call, and the control module controls the telephone module to reject the call.

[0087] B.4 The control module controls the VoIP client module to call the calling number through the VoIP server.

[0088] B.5 The proxy device user connects the call after receiving the call from the VoIP server.

[0089] B.6 The control module ju...

Abstract

The invention discloses a VoIP technology based phone agency device and a method for making and answering a call by using the same, the device is composed of a phone module being controlled by a control module to forward information between a telephone network and the control module; a VoIP client module one and a VoIP client module two, which are controlled by the control module to forward information between a VoIP server and the control module; the control module for controlling the phone module, the VoIP client module one and the VoIP client module two to create, maintain and release a communication link, and forward information between the phone module and the VoIP client module one and between the VoIP client module one and the VoIP client module two. With the device and the method provided by the invention, making and answering calls at a roaming site costs little, and the device is easy to implement, simple in structure and low in acquisition 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 ...
