Abstract
When communications are performed by connecting a non-SIP information terminal device in which SIP is not supported to a SIP converter connected to a communication line via a line terminating device, the SIP converter performs establishment and disconnection of a SIP session, and transmission of a SIP message on behalf of the non-SIP information terminal device.
Claims10
A communication apparatus for enabling communication between a first terminal device that is not compatible with SIP and a second terminal device that is compatible with SIP, wherein
- the communication apparatus:
- in response to the first terminal device turning on a terminal ready signal, turns on ready-for-sending signal to the first terminal device;
- receives a telephone number sent as a CRN command from the first terminal device in response to the turning-on of the ready-for-sending signal;
- identifies the second terminal device as a communication partner based on the telephone number received as the CRN command;
- and
- transmits an INVITE command to the identified second terminal device.
A communication apparatus for enabling communication between a first terminal device that is not compatible with SIP and a second terminal device that is compatible with SIP, wherein
- in response to the first terminal device changing a terminal ready signal from OFF to ON, the communication apparatus transmits an INVITE command to the second terminal device that has been designated in advance as a communication partner.
A communication apparatus for enabling communication between a first terminal device that is not compatible with SIP and a second terminal device that is compatible with SIP, wherein the communication apparatus:
- on reception of a notification from a third terminal device, transmits an INVITE command to the second terminal device that has been designated in advance as a communication partner to establish an SIP session with the second terminal device;
- and
- transmits data that has been received from the first terminal device to the second terminal device using the SIP session.
A security system comprising:
- a monitoring device that detects an intruder;
- a camera;
- a terminal device that is compatible with SIP;
- and
- a communication apparatus that communicates with the camera using a protocol other than SIP and communicates with the terminal device using SIP, wherein
- the communication apparatus:
- establishes an SIP session with the terminal device on reception of a notification from the monitoring device;
- and
- transmits information of the camera to the terminal device using the SIP session.
