Modem and method for processing talking packet

Abstract

The invention discloses a modem used for realizing that a software telephone uses a communication line of an entity IP (Internal Protocol) telephone to establish talking. The modem comprises a communication module, a judgment module, a recording module and a modification module, wherein the communication module is used for receiving a talking request packet from the software telephone, and also transmitting the modified talking request packet to a server and receiving a talking response packet from the server; the judgment module is used for judging whether the talking request packet containsa special mark or not and whether the entity IP telephone is in an idle state or not; the recording module is used for recording a source IP address of the talking request packet when the entity IP telephone is in the idle state; the modification module is used for modifying the source IP address of the talking request packet to be an IP address of the entity IP telephone. The modification modulemodifies a target IP address of the talking response packet to be a source IP address recorded in the recording module, and the communication module resends the modified talking response packet to the software telephone so as to establish the talking.

Description

technical field [0001] The invention relates to network communication, in particular to a modem and a method for processing communication packets. Background technique [0002] The existing modem provides at least two ports, which are respectively connected with the IP telephone and the personal computer, and connected with the server through the cable TV network and the VoIP network, and are used to process the call packets of the IP telephone and the personal computer. However, existing IP telephones with multimedia functions such as recording and voice message are expensive and have limited functions, while personal computers themselves have the functions of multimedia functions and softphones. [0003] However, the existing modem cannot solve the problem of using the communication line of the IP phone to establish a call by the software phone in the personal computer. Contents of the invention [0004] In view of this, it is necessary to provide a modem for enabling t...
