And what returns prtpengine at log when changing this packet.

Returning to SIP proxy: d3:sdp316:v=0#015#012o=root 1195474335 1195474335 IN IP4 2.10.39.16#015#012s=Asterisk PBX 12.6.1#015#012c=IN IP4 2.10.39.16#015#012t=0 0#015#012m=audio 30614 RTP/AVP 8 3 0 101#015#012a=rtpmap:8 PCMA/8000#015#012a=rtpmap:3 GSM/8000#015#012a=rtpmap:0 PCMU/8000#015#012a=rtpmap:101 telephone-event/8000#015#012a=fmtp:101 0-16#015#012a=ptime:20#015#012a=maxptime:150#015#012a=sendrecv#015#012a=rtcp:30615#015#0126:result2:oke

So it looks like that Destination sets from second append_branch at second step (to UDP)  and body sets as body of first step (for WS packet)

Do you mean that the outgoing packet contains two SDP bodies? This has
been discussed and solved in this thread:
