Internet telephone network system, network access method and talking device adapter

Abstract

There was a problem that the Internet telephone adapter connected with the existing telephone set could not make a call as a normal telephone when the Internet telephone could not be utilized and was switched to a public line. In the telephone device adapter connected to the public line and IP network, the public line signal transceiver unit 1100 inputs the call information and the telephone number from the telephone set 10, and the connection destination determination unit 200 obtains the IP address corresponding to the above telephone number to generate route selection information , to send the route selection information to the line connection switching unit 100 . The line connection switching unit 100 selects either the route of the public line 13 or the route from the IP network communication processing unit 5000 via the IP network 14 based on the route selection information, and sends the call information to the telephone 20 .

Description

technical field [0001] The present invention relates to an Internet telephone network system in which a telephone as a communication device is connected to a communication device adapter, the communication device adapter is connected to an IP network and a public line, and any one of the public line and the IP network is used for conversation between the telephones. Moreover, it also involves setting up a relay server in an environment where the telephone is protected by a firewall, and in an environment without firewall protection, the relay server relays the conversation between the telephones, so as to realize the connection between the telephones beyond the firewall. Internet telephony network system for calls. Background technique [0002] Currently, Internet telephones that transmit and receive voice data as IP (Internet Protocol: Internet Protocol) packets through the Internet and intranets that are computer networks are replacing existing telephones using public line...

AI Technical Summary

Problems solved by technology

[0010] The 2nd, for the existing Internet telephone adapter, in order to be able to use the Internet telephone to make a call through the IP network, it is necessary to register and set the IP address of the telephone adapter on the receiving side into the own telephone adapter in advance, so the user can input the IP address of the telephone adapter. It will take a certain amount of time, which is also a problem

[0012] Third, there is still a problem in the existing Internet telephone adapter that it is impossible to hold a conference call that needs to be authenticated and managed by three or more participants who participate in the call through the IP network under the condition that only the telephone set and the adapter connected to the telephone set are equipped. problems

[0014] Fourth, the existing Internet telephone adapter also has a problem of increasing the installation cost of the device itself because it needs to install a setting input and output device dedicated to setting internal information required for maintenance work.

[0016] Fifth, the existing Internet telephone adapter still has a problem that it is difficult to ensure real-time characteristics in voice data communication processing

[0018] Sixth, the existing Internet telephone adapter also has a problem that it is generally impossible to use any UDP port in the processing of voice data communication through the firewall.

[0022] Seventh, the existing Internet telephone adapter also has a problem that the voice data packet as the communication object is equipped with various protocol headers larger than the voice data itself, which tends to increase the network traffic.

[0030] Eleventh, another problem with existing Internet telephone adapters is that even when a public line with a number display function (number display function) service agreement can be used, or even when an Internet telephone via an IP network is being used , or when it cannot be used, the number display function on the communication device cannot be used
