Corey Farrell updated ASTERISK-23134:
-------------------------------------

    Attachment: udptl-selinux-compat.patch

Looks like udptl has the same issue.  I've done a compile only test for the udptl patch.  Unlike RTP I don't have a way to test udptl.

>         Environment: CentOS 6, SELinux enabled with default settings

> When a port is reserved by SELinux, ast_bind to that port causes errno == EACCES.  Instead of trying the next port ast_rtp_new gives up.
> As an example CentOS 6 default SELinux reserves udp port 10080-10082 for Amanda backup.  This overlaps the rtp.conf default port range, causing random failed call setup's.
