Hello,
there is no parameter to disable adding new r-uri as a contact, I
suggested to be added.
Meanwhile I looked at the code and there could be an option to get it work.
Append a branch after each next_gw() and before sending reply, do
"revert_uri();" (ie., instead of dropping last branch do revert_uri()).
Cheers,
Daniel
