Hi Armin,

I was trying with IPv6 for sometime due to the NAT headache in IPv4. That goes with another story in conversion from IPv6 to IPv4. Registering with a IPv6 tunneling server. Install tunneling client. Opening the ports in the router. ( I'm behind firewall ) Atlast I could make it to work only to ping my own machine.

I think it should work find with DMZ mode.

Hello,

I want to build a system that will allow to make SIP calls between IPv4-only UAs and IPv6-only UAs.

Has anybody tryd this before? Any success? Is it possible with SER? In the RTP-streams between the IPv4-UA and the IPv6-UA there must be a "black box" converting the IPv6 stream to a IPv4 stream and vice versa. Could this be a back-to-back server? Are there any other ways?

Thanks for any help Armin

Look at the portaone RTP proxy, it could be used as a black box. There's some comments in the readme. http://www.voip-info.org/wiki-Portaone+RTPproxy

I think SER with portaone could be a good choice. If Asterisk had IPv6 support, it would also work.

Good luck, keep us posted on your progress.
