[Guido Falsi (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=233907#comment-233907 ] 

Guido Falsi commented on ASTERISK-26617:
----------------------------------------

If this also applies to linux then the commit I reference in the report should be really checked out.

It removes a useful option (forcing a peer on IPv6) and actually creates a problem where IPV6 is not available.

My patch is more an hack than a real fix to the original problem.

> 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:
