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

             Summary: RTP regression in 13.13.0-RC1
                 Key: ASTERISK-26617
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-26617
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_rtp_asterisk
    Affects Versions: 13.13.0
         Environment: FreeBSD 11.0-RELEASE, no IPV6 configured on machine.
            Reporter: Guido Falsi


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:
