For complete rtpengine documentation, take a look at the rtpengine README.md:
https://github.com/sipwise/rtpengine
There are new feature added with each new rpengine release.
The opensips rtpemgine module documentation (with respect to flags)
should be seen as a starting point.and the rtpengine README is the
official documentation.. The opensips rtpengine module provides a
mechanism to pass those flags as strings to the rtpengine instance.
Maybe we should add this to the documentation.

Ovidiu Sas
