Can anyone help out?  I need to insert a Plus in the the Diversion header User field.  The Mask fields listed are all fixed length.  The client has a veraible length dial plan.

You can try something like the below (haven't tested it):

1
2M = {}
3    function M.outbound_INVITE(msg)
4        local div = msg:getHeader("Diversion")")
5        local uri = string.gsub(div, "<", "<+")
6        msg:modifyHeader("Diversion")", uri)
7    end
8return M
