[Serusers] Some Module Questions

Hi, Context: I am currently writing a module that allows me to connect to a policy server -- not unlike CPL. It essentially routes the message out to the server and then receives a response. I get the message out ok, and will receive a complete sip message back. The module main function is called in the ser.cfg. Here are my questions: 1) how do I get a message that I have received -- say in char *msg_buf -- to be the message that is used for further routing? The policy server might have changed any header fields or even created a (or several) completely new message(s). 2) can the module send back intermediate messages, such as 1xx info, while it is still continuing its work? This is to provide the user with feedback should things take while ... 3) I also want the module to react to SIP response messages (4xx and so). I assumed providing a response_function would do this, but apparently not (I had a simple one which was just LOGging some text to the system log, but it never did create any entries). So how can I do this? thanks, Stephan -- Dr Stephan Reiff-Marganiec Research Fellow Department of Computing Science; University of Stirling email: srm(a)cs.stir.ac.uk tel: 01786 46 7448 -- The University of Stirling is a university established in Scotland by charter at Stirling, FK9 4LA.
