Abstract

According to one embodiment, an interface apparatus includes a connector capable of connecting a plurality of SIP terminals and a SIP network to a port, a first processor which executes an exchange processing to the plurality of SIP terminals, a second processor which executes an exchange processing to the SIP network, a memory which stores a terminal ID for specifying each of the plurality of SIP terminals, and a sorting module configured to refer to a stored content of the memory based on sender identification information in a control signal relating to an exchange received by the connector, and sort the control signal to the first processor or the second processor based on a reference result of the memory.

Claims

1. An interface apparatus comprising:

a connector capable of connecting a plurality of session initiation protocol (SIP) terminals and a SIP network to a port, the SIP terminals including a communication function specified by SIP;

a first processor which executes an exchange processing to the plurality of SIP terminals;

a second processor which executes an exchange processing to the SIP network;

a memory which stores a terminal ID for specifying each of the plurality of SIP terminals; and

a sorting module configured to refer to a stored content of the memory based on sender identification information in a control signal relating to an exchange received by the connector, and sort the control signal to the first processor or the second processor based on a reference result of the memory.

2. The interface apparatus according to claim 1, further comprising a registering module configured to register the terminal ID for specifying the SIP terminal into the memory based on a registration request message arriving from the SIP terminal, when a SIP terminal not registered to the memory is connected to the connector.

3. An exchange apparatus comprising:

an interface apparatus which accommodates a plurality of session initiation protocol (SIP) terminals each including a communication function specified by SIP and is capable of connecting the SIP network; and

an exchange controller which makes the interface apparatus execute an exchange processing relating to said plurality of SIP terminals or the SIP network,

wherein the interface apparatus includes;

a connector which connects the plurality of SIP terminals and the SIP network to a port;

a first processor which executes an exchange processing to the plurality of SIP terminals;

a second processor which executes an exchange processing to The SIP network;

a memory which stores a terminal ID for specifying each of the plurality of SIP terminals; and

a sorting module configured to refer to a stored content of the memory based on sender identification information in a control signal relating to an exchange received by the connector, and sort the control signal to the first processor or the second processor based on a reference result of the memory.

4. The exchange apparatus according to claim 3, further comprising a registering module configured to register the terminal ID for specifying the SIP terminal into the memory based on a registration request message arriving from the SIP terminal, when a SIP terminal not registered to the memory is connected to the connector.

5. A control method for use in an interface apparatus capable of connecting a plurality of session initiation protocol (SIP) terminals a SIP network to a port, the SIP terminals including a communication function specified by SIP, the method comprising:

storing a terminal ID for specifying each of the plurality of SIP terminals connected to the interface apparatus in a memory;

referring to a stored content of the memory based on sender identification information in the control signal, when a control signal relating to an exchange arrives;

executing an exchange processing for the plurality or SIP terminals, when the sender identification information and the terminal ID in the memory agree with each other as a reference result of the memory; and

executing the exchange processing for the SIP network, when the sender identification information and the terminal ID in the memory do not agree with each other as a reference result of the memory.
