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?
