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.

  1. To achieve interoperability of VoIP systems using SIP in both Multi-vendor and Multi-provider environments.
  2. To prepare the test environment and evaluate interoperability as follows.
    1. Provide the minimum requirement of evaluation and test specifications
    2. Develop the test tool (software) compliant with the evaluation and test specifications.
    3. Hold an interoperability test events.
    4. Provide a test-bed for interoperability verification/evaluation
  3. To cooperate for global alliances and business activities to execute the above-mentioned tasks.
