Hi I'm attempting to use ICE to be able to present all possible RTP transports to peers.
16.28.0~dfsg-0+deb11u2 (I know it's old, but unfortunately Asterisk was removed from debian 'stable' and the version in 'sid' is just broken (opus + voicemail don't work anymore). But I ran into an issue when the peer is running rtpengine: Asterisk offers: a=candidate:H9da13901 1 UDP 2130706431 157.161.57.1 13104 typ host a=candidate:H1054cffa 1 UDP 2130706431 2001:4060:dead:beef::1 13104 typ host a=candidate:He9b56028 1 UDP 2130706431 fe80::5054:ff:fea2:9057 13104 typ host a=candidate:H9da13901 2 UDP 2130706430 157.161.57.1 13105 typ host a=candidate:H1054cffa 2 UDP 2130706430 2001:4060:dead:beef::1 13105 typ host a=candidate:He9b56028 2 UDP 2130706430 fe80::5054:ff:fea2:9057 13105 typ host To me this looks like every candidate is duplicated on port +1 rtpengine complains: [ice] Priority collision between candidate pairs sKy64vK5pY86kc9w:H9da13901:2 and sKy64vK5pY86kc9w:H9da13901:2 - ICE will likely fail And indeed RTP starts on IPv6 as proposed by H1054cffa but as soon as a re-invite is processed rtpengine switches to I guess H9da13901 and rtp dies. Why is asterisk proposing two ports per ip protocol? Is there a way to configure this more precisely? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________ -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
