VoIP (Voice over IP) technologies are becoming popular
rapidly in anywhere for example homes, enterprises, and
ISP networks, but we can hardly say that VoIP systems
are interoperable in a multi-vendor or multi-provider
environment, because the vendors and providers tend to
develop their products or services on their own way and
there is less establishment of interoperability.
For VoIP and its multimedia service to be as popular as current telephone system and become widely used in public or industrial applications, we believe interoperability both between the venders and the providers will be the minimum prerequisite for success.
According to the necessity of the collaboration between various related organizations in worldwide scale --especially in Asia area--, we establish "VoIP System Interoperability Task Force" to be a part of the activities required.
The purposes of the activities by this Task Force can be summarized as the following three.
- To achieve interoperability of VoIP systems using SIP in both Multi-vendor and Multi-provider environments.
To prepare the test environment and evaluate
interoperability as follows.
- Provide the minimum requirement of evaluation and test specifications
- Develop the test tool (software) compliant with the evaluation and test specifications.
- Hold an interoperability test events.
- Provide a test-bed for interoperability verification/evaluation
- To cooperate for global alliances and business activities to execute the above-mentioned tasks.
Japan Network Information Center (JPNIC) is the National
Internet Registry in Japan that provides allocation and
registration services of IP addresses and AS
numbers. JPNIC also performs activities for the public,
such as overseeing administration of the JP domain names
in the public interest, and coordinating with the
Internet Corporation for Assigned Names and
JPNIC contributes to the society by providing Internet-related information as an information hub, and performing research, education and enlightenment activities.
JPNIC is a non-profit, membership-based organization that supports smooth administration of the Internet.
