<p>The selection of rtpengine instance is done when the call is initiated, after that should be a sticky behaviour, because the replies have to go to the same instance, as well as BYE or other messages within early/established dialog.</p>
<p>What it seems you are looking for is high availability, so in case a rtpengine goes does another instance can take over the rtp relay sessions. This should be possible with rtpengine and redis, see the docs of rtpengine application.</p>
<p>Considering the above, specially the stickiness needed between request and reply, plus for BYE/CANCEL, changing the current behaviour makes no sense, but being open source, one can contribute such alternative controlled by an modparam.</p>
<p>It is not a bug right now, but how it is expected to work.</p>
