%% Purpose: This module takes the role of the main megaco module for
%% the transport module. It is used when delivering
%% received messages. The purpose is to be able to do
%% various forms of filtering before passing the message
%% the the megaco stack (by calling the megaco module).
%% It can be controlled with the following flags:
%% allow_recv_message - Shall the received message be
%% delivered.
%% extra_transport_info - Provide extra info from the transport
%% module.
%%----------------------------------------------------------------------
-module(megaco_test_deliver).
