-----------------------------------------

[~pguyot] , I've opened the issue. Please note that Asterisk issues for non-Linux operating systems are handled under "extended support", which means that the broader community supports the issue. The quickest route to resolution is usually to submit a patch yourself. Otherwise you are waiting to see if someone else is interested in taking on the problem.

If there is any additional debug that would help someone in resolving the issue, please attach it when you are able. Thanks.

>          Issue Type: Bug
>      Security Level: None
>          Components: Resources/res_pjsip_sdp_rtp
>    Affects Versions: 13.17.0
>         Environment: FreeBSD and any OS where an IPv6 socket cannot reach IPv4 hosts by default.
>            Reporter: Paul Guyot
>
> This issue is similar to ASTERISK-16545 but with pjsip.
> When creating an RTP socket, create_rtp function in res_pjsip_sdp_rtp.c uses to determine the IPv4/IPv6 family, by default, address_rtp, which is an IPv6 socket if IPv6 is enabled on the host.
> Yet, the endpoint might be an IPv4 host and therefore not reachable with IPv6.
> Additionally, Asterisk does not log that send_to failed.
