Hi,<div dir="auto"><br></div><div dir="auto">A very long time since I Iast posted on here. I have recently moved to Asterisk 16 and have encountered a problem trying to connect via ipv6-udp transports. Looking at the traffic it seems that Asterisk only ever queries for DNS A records. Stepping through sip_resolve in pjsip_resolve.c I get to line 592. The code looks like this. I apologise for the formatting. I cannot work out how to get this mail client to do preformatted text.</div><div dir="auto"><p dir="ltr">if ((type == PJSIP_TRANSPORT_UNSPECIFIED && sip_transport_is_available(PJSIP_TRANSPORT_UDP6)) ||<br>
sip_transport_is_available(type + PJSIP_TRANSPORT_IPV6)) {<br>
res |= sip_resolve_add(resolve, host, T_AAAA, C_IN, (type == PJSIP_TRANSPORT_UNSPECIFIED ? PJSIP_TRANSPORT_UDP6 : type + PJSIP_TRANSPORT_IPV6), target->addr.port);<br>
}<br></p></div><div dir="auto">At this point only a A type record query has been added. The transport type is already set to PJSIP_TRANSPORT_UDP6. So adding PJSIP_TRANSPORT_IPV6 to it results in a nonsense transport type. As PJSIP_TRANSPORT_IPV6 is 128 surely it would be better if this was a bitwise OR instead of an ADD.</div><div dir="auto"><br></div><div dir="auto">What am I missing here?</div><div dir="auto"><br></div><div dir="auto">Roger</div>
