Method, system and IAD (Integrated Access Device) for processing voice message

Abstract

The invention is suitable for communication fields and provides a method, a system and an IAD (Integrated Access Device) for processing a voice message. The method comprises the following steps of: intercepting a message voice pack of a remote user in a PSTN (Public Switched Telephone Network) network or an IP (Internet Protocol) network by the IAD; extracting voice data in the voice pack by the IAD; and storing the voice data into a local voice mail database by the IAD after preprocessing the voice data. According to the method, the system and the IAD for processing the voice message, through a manner that a voice mail is arranged in the IAD, a method for accessing the voice mail by three manners including a remote phone, a local phone and a Web page is realized, the requirements of different users on voice mail services on various occasions can be met, and the dependence of a pure software voice mail on a PC (Personal Computer) machine can be removed.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a voice message processing method, system and IAD. Background technique [0002] At present, the method for providing the voice mail service can be divided into two types, one is the long-distance voice service for fixed-line telecommunications users of the PSTN (Public Switch Telephone Network, public switched telephone network) network and IP telephone users of VoIP (Voice Over IP) mailbox; the other is a PC-based pure software VoIP local voice mailbox for soft IP phone users. [0003] Regarding the first method of providing voice mail services, such as figure 1 The network topology described: [0004] The voice gateway / PBX (Private Branch Exchange) is the user-side access device, which realizes the access of the telephone user to the VoIP or PSTN network. PSTN or VoIP operators open the voice mail service system to provide value-added services. The system stores the vo...

AI Technical Summary

Problems solved by technology

[0024] 2) The voice message is stored on the remote server, and it is impossible to listen to and operate the voice mailbox message without being connected to the Internet, and the security and reliability of the voice message are not high;

[0025] 3) The user can only remotely listen to and manage messages in the voice mailbox by pressing buttons according to the prompt tone of the phone, and can only remotely set parameters such as the voice mailbox mode and password and remotely record personalized greetings, which is a single method;

[0026] 4) It is necessary to apply for an additional voicemail number, which is inconvenient to memorize and operate;

[0028] 6) The recording time and message retention time are limited by the operator and cannot be controlled by the user;

[0029] 7) The message notification method is telephone or automatic pager. If the user does not want to listen to the message for the time being and the voice mailbox keeps calling, it will cause some trouble to the user, and the use of this message notification method will increase additional communication costs

[0042] 1) The voice mailbox is oriented to VoIP users of the IP network, and cannot handle messages of analog voice signals of the PSTN network;

[0043] 2) Traditional PSTN services, such as voice calls, fax, Modem, etc., cannot be realized while providing voice mail services;

[0044] 3) The voice mailbox uses a PC as the carrier, resulting in excessive dependence on the PC, and if the PC is used as a shared voice mailbox server within the group, the long-term stable operation of the PC is required;

[0045] 4) It is necessary to apply for an additional voice mailbox number from the VoIP service provider, which is inconvenient to memorize and operate;

[0046] 5) It does not support the operation of recording personalized greetings on local phones and remote phones. You can only use the recording tool of the PC to record greetings in a specific format and store them in a certain directory on the PC;

[0047] 6) It does not support the operation of listening to and managing messages on local phones and remote phones. In this method, the voice files of messages can only be accessed by a Web browser or a PC client, and then output through the audio port of the PC;

[0048] 7) It does not support the ability to set voicemail parameters such as voicemail mode, message retention time, message duration, PIN code, greeting selection, etc. by means of local phones, remote phones, and Web management pages;

In this way, it is necessary to use software to implement a large number of encoding and decoding tasks, which increases the difficulty of development and affects the efficiency of software execution and the timeliness of voice transmission.

In addition, since most speech coding algorithms are lossy compression, the speech quality after codec conversion will be degraded or distorted;

[0050] 9) As mentioned above, since the encoding format of the communication is not uniform, if the negotiated communication format is a voice encoding format with a high compression ratio such as G.723.1 and G.729, and the INBAND mode of the RTP in-band transmission is used to transmit the DTMF button, At this time, the DTMF button detection will be distorted, and the user cannot realize the interactive operation of the button;

[0051] 10) The pure software VoIP voice mailbox cannot notify the user of new messages, and the user can only actively check whether there are new messages through the Web or PC client
