Hi All, 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 was working absolutely 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 any more 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: [May 25 19:18:18] WARNING[3674] chan_sip.c: Address remapping activated in sip.conf but we're using IPv6, which doesn't need it. Please remove "localnet" and/or "externaddr" settings. I think that is a bug because the externaddr is used correct during the outbound calls. My Asterisk version is 1.8.3.3! Is somebody able to help me with that issue? Should I write a bug ticket for that? best regards Christoph -------------- next part -------------- An HTML attachment was scrubbed...
