check why AmRtpStream::relay_raw is not enabled for the UDPTL stream.
maybe try something like this:
diff --git a/core/AmB2BMedia.cpp b/core/AmB2BMedia.cpp
index b83d5aa..5c76def 100644
--- a/core/AmB2BMedia.cpp
+++ b/core/AmB2BMedia.cpp
@@ -495,7 +495,10 @@ void AudioStreamData::setReceiving(bool r) {

AmB2BMedia::AmB2BMedia(AmB2BSession *_a, AmB2BSession *_b):

itselves
Normally, it should be set in AmB2BMedia::updateRelayStream.
