In addition, when address information is transmitted, whether or not address information can be transmitted is determined based on communication capability information indicating communication capability related to browsing display of a digital TV terminal in a partner user terminal device. Transmission of the correct address information can be avoided. At this time, if there is no communication capability related to the browsing display of the Web page, this may be notified to the user on the transmission side.
Further, whether or not the address information can be transmitted based on the communication capability information is determined on the call control server or the partner user terminal side that manages the communication capability information, and the determination result is returned to the address information transmission side. Good.

Further, since the communication capability information is managed by the call control server, it can be managed with high security, and unauthorized acquisition of the communication capability information by a third party can be avoided.
Furthermore, since the communication capability information is transmitted to the call control server in response to the standby setting operation by the user on the address information receiving side, the standby setting operation is not performed for a partner whose user's permission cannot be obtained. As long as the communication capability information is not transmitted, it is determined that the address information cannot be transmitted due to the lack of the communication capability information, and therefore transmission of unapproved address information can be rejected. At this time, the information indicating whether or not the address information can be received from the other party of the VOIP call in the communication capability information may be deleted every time the VOIP call ends, and higher security is obtained.

In the above, the case where there are two user terminal devices has been described for ease of explanation. However, even when three or more user terminal devices are connected to the VOIP network, the present embodiment is performed in the same manner as described above. Applicable. Furthermore, even when a VOIP call is performed between three or more user terminal devices, the present embodiment can be applied in the same manner as described above, and any one user terminal device can be used as a plurality of other user terminal devices. On the other hand, desired address information can be transferred by the address information transfer unit of the call control server, and the same effect as described above can be obtained.
Further, the case where the address information is transmitted from the calling side of the VOIP call has been described as an example. However, the present invention is not limited to this, and the same applies to the case where the address information is transmitted from the receiving side of the VOIP call. The present embodiment can be applied, and the same effects as described above can be obtained.

Further, when transmitting the address information, the communication capability information of the other party may not be acquired from the call control server, but the communication capability information may be acquired directly from the other user terminal device. Management burden can be reduced.
In addition, when address information is transmitted, the case where the desired Web page is browsed and displayed and then the address information is transmitted has been described as an example. However, the present invention is not limited to this. When browsing and displaying, the address information registered in advance in the information management unit of the home GW may be transmitted.
