Btw, a few questions for further clarifications: if a call has
parallel forking and rtpengine offer is executed for each branch, one
is answered, but the other branch-sessions are not not deleted, what
does rtpengine? It times them out, or keeps them for the duration of
the call?
Those branches would remain open. When the call is finished, it will
depend on how the delete is executed: if the delete is done from the
side which branched the call (side A, caller), then the entire call
including other branches are deleted. If the delete is done from the
opposite side (B, one of the branches), the other branches would still
remain open, keeping the entire call alive. The call would then
eventually time out depending on the config, but it might take a while.
Also in the case of parallel forking, if via-branch is not give to
rtpengine offer command, does the 2nd (and the next) rtpengine offer
command overwrite the previous one, so the rtpengine keeps only the
data from the last one?
Correct, with possibly some undesired side effects depending on which
flags were used (e.g codec changes).
