This sounds like an incompatibility between the version of the rtpengine control module on the Kamailio side and the version of rtpengine on the RTP proxy side.

Right around the time that the rtpproxy-ng -> rtpengine nomenclature change happened, there was also a significant change to the anatomy of the control protocol.

Be sure that you are using the latest version of Kamailio, where the module is called 'rtpengine', not 'rtpproxy-ng'.
