>      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.
