<p>Hi Daniel,</p>
<p>I reviewed the code and unfortunately, it does not cover the case when</p>
<ul>
<li>enable_double_rr=1</li>
<li>both UA are using the same IP and the same port and there is only one route inserted by record_route()</li>
</ul>
<p>To handle this case, see the patch I suggest below. Alternatively, we could set  enable_double_rr=2 I guess. What is your opinion ?</p>
