Voice over IP (VoIP) is widely used in IPv4 networks. VoIP in IPv6 networks on the other hand it is used quiet less. Through this test the team wants to find out whether VoIP can run easily on an IPv6 network. The goal of this test is to find out whether VoIP phone from different vendors can work together on IPv6. An interoperability test will be performed using various routers and switches from various vendors. First a IPv6 network consisting of several brands is built using VoIP phones which are connected to a switch.

How is this tested?
First we check whether the phones can connect via the same switch (in collaboration with the SIP server). If the VoIP phones can work together in a network the team can check whether the two different networks can communicate. This is actually a simulated scenario between offices, which are connected with each other through IPv6.

For more information on how the phones are tested read Testing the VoIP phones or check out the Test Document VoIPv6, Technical Design VoIPv6 and Technical Documentation VoIPv6.
