[asterisk-users] pjsip rtp_ipv6=yes but endpoint registered via ipv4 (IP4 contact infor)
Dear List I fear I stumbled over a bug in asterisk 13.14.1. My 'phones' are roaming around, sometimes some are connecting from ipv6 enabled networks, another time they are not. If a connection is ipv6 I would prefer to use ipv6 to avoid ipv4-nat problems. I have not specified a transport in the endpoint section, so that the appropriate transport which corresponds to the registration can be used. Now I have noticed, if an phone is registered from an ipv4 only endpoint and is performing an outgoing call, my asterisk server is answering with an IP4 RTP IPv6 address: Example: <--- Received SIP request (1235 bytes) from UDP:157.161.4.172:5060 ---> [...] v=0 o=MxSIP 0 20 IN IP4 157.161.4.172 s=SIP Call c=IN IP4 157.161.4.172 t=0 0 m=audio 6018 RTP/AVP 9 8 97 91 101 a=rtpmap:9 G722/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:97 CLEARMODE/8000 a=rtpmap:91 X-CLEAR-CHANNEL/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=sendrecv <--- Transmitting SIP response (914 bytes) to UDP:157.161.4.172:5060 ---> [...] v=0 o=- 0 22 IN IP4 2001:4060:dead:beef::1 s=Asterisk c=IN IP4 2001:4060:dead:beef::1 t=0 0 m=audio 16172 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 a=maxptime:150 a=sendrecv Errr... how should my client @ 157.161.4.172 send udp to 2001:4060:dead:beef::1? Also when I compare with a real IPv6 client I notice from the client: c=IN IP6 2001:4060:1:4133:204:13ff:fe30:2a80 from the Asterisk: c=IN IP4 2001:4060:dead:beef::1 Shouldn't that also be IP6 from the asterisk?

Remove it and give it a try. The option itself actually had the bug that you are seeing. -- Joshua Colp Digium, Inc. | Senior Software Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - US Check us out at: www.digium.com & www.asterisk.org

Hi Jushua> The rtp_ipv6 option is not needed, in current versions things will > automatically be updated to reflect the signaling. Remove it and give > it a try. The option itself actually had the bug that you are seeing.Ok, commented out rtp_ipv6 in the config and did try again: IPv6 Registered client. c=IN IP6 2001:4060:1:4133:204:13ff:fe30:2a80 Reply from * c=IN IP6 2001:4060:dead:beef::1 IPv4 registered client: c=IN IP4 157.161.4.172 Reply from * c=IN IP4 157.161.57.1 Perfect! It didn't occur to me to completely comment out that option as I believed it was needed for rtp to work over ipv6. Thank you for that exceptional quick help.
