IPv6 and IPv4 NAT not working

Asterisk Asterisk General
1

Hi All,

today I tried to play a little bit with IPv6 to test our VoIP quality software with IPv6 RTP streams.

I add “bindaddr=::” to the general section of the sip.conf and netstat shows that Asterisk is listing also on IPv6.

My Asterisk server is behind a IPv4 NAT and is working absolutly perfect.
But after my bindaddr change I got a problem with external calls.

I spend some time to investigate this issue and found out the outbound calls are working. The externaddr is used in the SIP INVITE.
If I received a inbound call the externaddr isn’t used anymore in SDP part of the answer from the Asterisk. The result is one way audio. In addition I saw the following message in the Asterisk log:

I think that is a bug because the externaddr is used correct during the outbound calls.

My Asterisk version is 1.8.3.3!

What should I do?

best regards

Hi All,

should I write a ticket for that or should I write to a mailing list?

I’d take it to the -users mailing list and if you don’t get some traction there, go ahead and open an issue.
