I don't see a real use case for the moment, it might be some behind or 
there is kind of exercising, however, you have to look at some simple 
modules to see the interface and how it interacts with the configuration 
file. Such modules can be xlog, dispatcher. You have to export a 
function in your module, that function will get as first parameter the 
SIP request received by OpenSER. You have to make it work in route and 
onreply_route blocks. Inside the sip message structure (struct sip_msg) 
you have two fields, 'buf' and 'len' where the content and lengts of 
received message are stored. Taking those, you can then write in a file.

To send, you can do usual C socked sending functions.

Cheers,
Daniel
