Would I be right in thinking that the reason I cannot immediately see the "path" value added by the add_path_received() call is because of how the lumps system works - i.e.
"lumps are stored in a list, and are only applied after the OpenSIPS script is fully executed and before the SIP message is relayed. Because of this, changes done on a SIP message are not immediately reflected on the SIP message upon further inspection ( eg. Adding a new header from the script and then checking for the header's existence )."
