Abstract

The invention is internet voice protocol device which includes subscriber line interface circuit used as the interface of telephone and internet voice protocol; relay which couples the telephone to public interchanging telecom or couple to internet voice protocol telecom through subscriber line interface selectively; process device which is used to judge that the dialed number of telephone through subscriber interface circuit is internet voice protocol dial or public interchanging telecom dial; when it is internet voice protocol dial, the process device puts the dial into internet voice protocol telecom, when it is public interchanging telecom dial, the process device control subscriber interface to generate a group of double audio multi frequency redial number; and double audio multi frequency coupling signal which is coupled to subscriber interface circuit and public interchanging telecom, receives the redial generated by the subscriber interface circuit and couples to interchangingtelecom.

Description

technical field [0001] The present invention relates to an application for providing call service, in particular to an Internet voice protocol device capable of simultaneously providing plain old telephone service (Plain Old Telephone Service) and Internet voice protocol (VoIP, Voice over Internet Protocol) services to users. Background technique [0002] With the development of communication systems, many communication technologies have been used to provide call services. These call services include old-fashioned telephone services and voice over Internet protocol services. The old-fashioned telephone service has been widely used in daily telephone communication. When the telephone is coupled to the Public Switched Telephone Network (PSTN, Public Switched Telephone Network), the user can be provided with the old-fashioned telephone service. Voice over Internet Protocol is a protocol that uses an open network (Network) to transmit audio and video. It uses packetized audio si...
