Yes, i've assigned a value in the script, just to try I've assigned $rU and
on the log of rtpengine I can see the value of "via-branch" valorized
correctly. I've also used the 'd' parameter in rtpproxy_manage() function.

I've also checked on the source code of rtpengine and the part regarding the
"parse & get" of via-branch value is commented...I'm using the master branch
of rtpengine.

This is the piece of code of call_interfaces.c where the via-branch
parameter is commented:
//bencode_dictionary_get_str(input, "via-branch", &viabranch);
