Jean-Denis Girard commented on ASTERISK-26617:
----------------------------------------------

I got exactly the same problem on a Linux machine with IPV6 disabled in kernel (4.8.7 from kernel.org locally compiled without IPV6 support). The system is Fedora 24. Applying the patch proposed by Guido resolved the issue for me, thanks Guido! So this is not FreeBSD specific.

>          Components: Resources/res_rtp_asterisk

> While everything worked fine with Asterisk 13.12.2 on this machines.
> Upgrading to 13.13.0-RC for routine testing, with all other factors the same, causes calls to be rejected with the following errors output to the console:
> [Nov 22 10:49:26] WARNING[101105]: res_rtp_asterisk.c:2400 int
> create_new_socket(const char *, int): Unable to allocate RTP socket:
> Protocol not supported
> [Nov 22 10:49:26] WARNING[101105]: res_rtp_asterisk.c:2665 int
> ast_rtp_new(struct ast_rtp_instance *, struct ast_sched_context *,
> struct ast_sockaddr *, void *): Failed to create a new socket for RTP
> instance '0x805647c30'
> [Nov 22 10:49:26] ERROR[101105]: res_pjsip_sdp_rtp.c:184 int
> create_rtp(struct ast_sip_session *, struct ast_sip_session_media *):
> Unable to create RTP instance using RTP engine 'asterisk'
> Some further testing indicates asterisk is trying to open an INET6 socket, while it should be using INET4 on this machines, which has no INET6 configured. This is just a first finding, I'm still investigating more.
> At a first look the problem looks related to this commit:
