<h4>Description</h4>
<p>If Kamailio sends a 301/302, the current dset is added as Contact header automatically. The feature in this PR will optionally extend this Contact header with more information.</p>
<ul>
<li>The path vector for each contact can be added as a Contact-uri Route header (rfc 3327 conformant).</li>
<li>The branch flags can be added as a Contact-header parameter (non-standard).</li>
</ul>
<p>In addition, the get_redirects function is extended to optionally parse the new flags parameter. The Route header can be extracted from the r-uri in the script.</p>
<p>The new functionality must be enabled with module parameters, by default the behavior is unchanged.</p>
