SIPML5 and IPV6 Support

[DHAVAL INDRODIYA]

Dear All,

I am running demo for SIPML5 + Asterisk (14.5.0) without any issue and it is working for most of the personal computer.
Recently I noticed one issue with Apple Machine which network is in IPV6 and When I make a call from that machine We cannot here anything back from my asterisk server although signaling are fine and call also connected.

After call connected there is no voice from B-Leg of call on browser and no media packets are flowing from browser to asterisk server.

Here is First Invite Packet from SIPML5 on chrome browser with ICE candidate is filled with IPV6 Address.

Now  If I dial from same browser same machine using IPv4 Network call connects and voice also passed.

Is it something we need to do with IPV6 Support ?

Do TURN server from numb.viaginie.ca solved this problem

Do I need to put my own TURN server to relay IPV6 and IPV4 packets ?

Will FreeSwitch solve this issue?

Do let me know if there is any other workaround.

Any help appreciated.
