Yes, from what I’ve seen in the logs there are multiple branches

That's just one branch; the incoming call doesn't count. "Real"
additional branches are created by calling functions like "append_branch".
You should definitely ensure (by adding appropriate logging calls) that
"rtpengine_manage" is called exactly once per outgoing application/sdp
message, with all requisite arguments(*). Anything else is a recipe for
confusion. In my experience that's sufficient(**) to get it all working
quite nicely.
(*) "trust-address replace-origin replace-session-connection", plus
either RTP/AVP or RTP/SAVP
(**) unless the opposite end is broken. Right now, for instance, talking
to Zoom Europe requires a heap of "SDES-no-RANDOM_CRYPTO_ALGORITHM"
arguments, for both incoming and outgoing calls. Discovering that fix
was decidedly nontrivial.
