    <p><font size="-1">What I found was then if I appended branches then
        called force_send_socket() only the current branch went out on
        that interface, the other branches went out on a different
        interface.  It's not a problem I will re-structure my script, I
        was simply appending branches to create a ring group.</font></p>

      <tt>Hi, Adrian!<br>
        <br>
        I don't think you will find such a list.<br>
        Usually the idea is to do the changes that affect all branches
        in the main route, and if you want to do per-branch changes, do
        them in the branch_route.<br>
        Are you sure that force_send_socket() only applies to the main
        branch? If you call force_send_socket() in the main route, and
        then add a second branch, the messages leave on different
        interfaces?<br>
        <br>
        Best regards,<br>
      </tt>

        <p><font size="-1">I understand from the documentation that
            after calling append_branch() any further URI manipulations
            only apply to the main branch, but I am trying to understand
            what actions will still apply over all the branches.  For
            example I discovered that rtpproxy_offer() appears to affect
            all branches, but force_send_socket() only apples to the
            main branch.</font></p>
