Hello Theodor,
I looked into the provided trace.
It seems that the multi-part body is here making issues. The header part Content-Length is updated, but not the multi-part one.
There have been other issues with multipart body messages before, as its not used that often. It might be a bug/limitation in the rtpengine module. If nobody else comment you could open an issue about it to not forget
about it.
Cheers,
Henning
