System and method for treating network telephone transmission package

Abstract

The voice service servo-server of the present invention can be used to register network telephone and also can be used to record network actual position being distributed to the network telkephone tomake call between the network telephones connected smoothly. In addition, the calling package with telephone number of another network telephone will be transmitted by the network telephone accordingto transmission control protocol when the network telephone sends "registered package" to voice service servo-server and calls another network telephone, in order to let the voice service servo-server record the effective network actual position.

Description

technical field [0001] The present invention relates to the technology for processing network telephony transfer packets and the network telephone. The network telephone is, for example, an independent network telephone or a computer network telephone for voice transmission through a computer, and the network especially refers to the Internet. Background technique [0002] Due to the development of the Internet (Internet) and the low cost, the application of using the Internet to achieve voice communication has been continuously developed, and the simple and easy-to-use Internet phone has also been developed, and many voice communication protocols (VoIP communication protocols) have also been formulated. For example, the most commonly used communication protocol is H232. [0003] The existing voice communication protocol could originally meet the communication needs such as Internet telephony. However, due to the development of the Internet beyond expectations, the number of...

Problems solved by technology

[0011] After the Internet phone A finally obtains the virtual address IPE of the Internet phone E, it immediately transmits the "call phone E packet" whose destination is the address IPE (step S23), and the address converter B then transmits the "call phone E packet" For H232 server C, and H232 server C receives the "call phone E packet", it tries to connect to the address IPE, but because the address IPE is a virtual address, not a legal address of the Internet, so H232 server C Unable to process, so Internet phone A and Internet phone E cannot establish a connection

[0012] Currently, it is very common to use address translators in companies, or it is very common to use firewalls with address translators in companies, and even network service companies set up single or multi-layer devices with address translators to provide resources. The missing legal address is used by many different companies or individuals, so VoIP does not work smoothly

Of course, some people also propose to change the current voice communication protocol as a solution, or replace the existing address converter or firewall, but this solution involves a large number of hardware replacements, so it is difficult to solve the problem
