When the management apparatus remotely manages the IP telephone apparatus, the management apparatus transmits a session establishment message including a command indicating a request for remote management and the IP address of the own management apparatus to the IP telephone apparatus,
When the IP telephone device that has received the message recognizes a command indicating a request for remote management in the message, it generates a random number, and includes the random number, port information for accepting remote management of the own device, and the IP address of the own device. Return the set response message to the management device,
The management apparatus that has received the response message generates an authentication character string from the password stored in advance in common with the IP telephone apparatus and the random number in the received response message, and the port information port of the IP telephone apparatus To
The IP telephone device that has received the authentication character string generates a second authentication character string from the password stored in advance with the management device and the generated random number, and receives the authentication character string received from the management device. An IP telephone system, wherein a character string is compared with a second authentication character string generated by the own device, and if the character string is identical, remote management from the management device is accepted .

The IP telephone system according to claim 1, wherein at least a remote management start request command for starting remote management or a remote management end request command for ending remote management is used as the command indicating the request for remote management .

3. The IP telephone system according to claim 1, wherein the command indicating the request for remote management is set as an additional command to an INVITE message defined in the SIP protocol .
