<div dir="ltr">I found INFO about "b" flag for rtpproxy-ng module. It may solve my porblem, but as I understand, rtpengine not support this flag.<br>I thought about adiing rtpproxy handling after append_branch (something like branch_route) but con not find any info how to use it after branching... Does anybody help me to solve this issue, or give me an advice about this issue?
