It is the same on master branch -- I decided to do the backport after PR
1460:

  * https://github.com/kamailio/kamailio/pull/1460

Open an issue on Kamailio's github tracker so it can be analyzed by the
developer of rtpengine and come up with the best solution here.

Thanks for all the troubleshooting!

Cheers,
Daniel
