<p>My Kamailio master based test sip proxy has two rtpengine sets:</p>
<pre><code># sip-proxy_ctl rtpengine.show all
{
        url: udp:192.26.134.1:6050
        set: 0
        index: 0
        weight: 1
        disabled: 0
        recheck_ticks: 0
}
{
        url: udp:192.26.134.40:6050
        set: 1
        index: 1
        weight: 1
        disabled: 0
        recheck_ticks: 0
}
</code></pre>
<p>Config calls set_rtpengine_set() with two set argument followed by rtpengine_offer():</p>
<pre><code>set_rtpengine_set("1", "0");
rtpengine_offer("...");
</code></pre>
<p>Debug shows that sip proxy sends TWO offer commands to the<br>
rtpproxy in the first set 1 and NONE to the rtpproxy in the second set 0.</p>
<p>Debug at set 1 engine:</p>

<p>This looks like a bug to me, since according to README, rtpengine should first send the offer to an engine in the first set and then to an engine in the second set.</p>
