<p>PROBLEM TO BE SOLVED: To provide a packet processing method by which telephone communication can efficiently be processed in a CL type telephone network. SOLUTION: A node N10 transmits a packet P10. An object address is an IP 3 and a processing state set to the packet P10 is ST0. The packet P10 is transferred to a node N11 by referencing a routing table T1. The node N11 conducts decoding in response to the ST0 and the processing state is updated from the ST0 into an ST1 and the packet P11 is transferred to a processing node N12. A node N12 applies echo cancel processing in an incoming direction in response to the ST1, the processing state is updated from the ST1 to an ST2 and the packet P12 is transferred to a node N13. The node N13 transmits the packet P12 to other network in response to the ST2.</p> |
