Any ideas? Looks like some sort of circular dependency, I don’t think there’s a module missing. The only pjproject module I’m able to load is res\_pjproject.so. For the “embedded” pjproject I noticed there’s a set of patches, do they also need to be applied on the “external” pjproject sources? ---

The patches are not required. They are backports from PJSIP for bug fixes that have not yet gotten released by them. As for the load problem it should be res\_pjproject.so, then res\_pjsip.so, then res\_pjsip\_session.so, then everything else. The module loader should resolve these automatically. What distribution are you using? ---

You can’t bind a single transport to both IPv6 and IPv4 like that. You need to create two transports, one for IPv4 and one for IPv6. As it is it is creating an IPv6 one and thus there is no transport to send an IPv4 request out on. It certainly shouldn’t crash as a result of that for the qualify like that so file an issue[1].

You have to create separate transports regardless, that’s not going to change. PJSIP fundamentally works that way. On the Asterisk side work has been done to properly support dual stack. The latest releases support this. ---

To clarify in regards to the patch: it made it so that you could create a transport and bind it to “::” to listen on IPv6, without knowing the IPv6 address of the system. Using this you can create two transports - one bound to “::” and one bound to “0.0.0.0” ---

Yep understood - 2 separate transports is not a problem, not being able to use [::] is a major pain though. Thanks for your help.
