    摘要： A system and method to change codec information to provide a coloring service in a Voice over Internet Protocol (VoIP) terminal uses different compression methods depending on a calling state and a call connecting state between the VoIP terminals so that a more efficient coloring service is provided. The system for changing codec information includes a gateway adapted to compress ring back tone data in a calling state and to compress voice signal data in a call connecting state between communication terminals according to preset different compression information and to transmit both data to a receiving terminal.

    摘要： A method for guaranteeing Quality of Service (QoS) using bandwidth reservation in a switch includes: establishing a MAC table including MAC addresses of terminals connected to each port of the switch and an identifier indicating whether or not the corresponding terminal is a VoIP terminal; calculating a VoIP bandwidth necessary for each port based on information of the MAC table, calculating a ratio of an entire bandwidth to a bandwidth equal to the entire bandwidth minus the VoIP bandwidth, and setting the ratio as a port ratio of the switch; determining whether or not the corresponding packet is a VoIP packet by filtering the MAC address of the corresponding packet upon an arbitrary packet of the switch being input; and passing the corresponding packet upon a determination that the corresponding packet is a VoIP packet, and passing the corresponding packet only when the bandwidth of the corresponding packet is within a permissible limit of the set port ratio by performing port ratio control upon a determination that the corresponding packet is not a VoIP packet.

    摘要： A call setup method and terminal in an IP network, in which in response to a request for an outbound call from a first terminal, it is identified whether or not an index matching an identification of a second terminal exists in a matching table. The identification of the second terminal is inputted at the request for the outbound call. If the index matching the identification of the second terminal exists in the matching table, a call initialization message is directly transmitted to the second terminal. In response to call setup, a call state synchronization message is transmitted to a call manager.

    摘要： In a Voice over Internet Protocol (VoIP) terminal supporting an optimal intercom service and a session connecting method thereof, a VoIP terminal announcement module of the VoIP terminal performs an announcement process by transmitting address information of the VoIP terminal to other terminals located in a same network, and acquires address information of said other terminals. If the address information acquired by the VoIP terminal announcement module includes information of a counterpart terminal called by a user, a call controller sends a session connecting invite message directly to said counterpart terminal using the acquired address information of the counterpart terminal. As a result, it is possible to provide intercom service to a user without going through an external SIP proxy server.
