    197197Therefore, to support IPv6-IPv4 interoperability in NAT64 environment: 
    198198 1. Our RECOMMENDATION is that when the client is put with an IPv6-only connectivity, the SIP server must also support IPv6 connectivity. For the media, user needs a "dual stack" TURN (a TURN server which supports IPv6 connectivity and able to provide an IPv4 relay address upon request). Then all the application needs to do is enable ICE and use TURN (support for dual stack TURN is only available in PJSIP 2.6 or later). 
    199  2. If 1) is not possible (no IPv6 server or not desirable to use TURN), we will need to replace all IPv6 occurences with IPv4 in the SIP messages and SDP. This feature is available in release 2.7.

    200200  a. You need a STUN server which resides in an IPv4 network. Then set your {{{pjsua_config}}} to try IPv6 resolution of the STUN servers. 
    201201  b. Create UDP6 transport to get an IPv4-mapped address from the above STUN server.
