[reSIProcate] Where can I find these implementations?

[John Draper <lists@xxxxxxxxxxxxxxxx>]

in SipSession.hxx,  this class definition is listed:

class SipSession
{
  public:
     void processRequest(SipMessage* msg);      // Where can I find 
where this is implemented?
     void processResponse(SipMessage* msg);    // And this?

    < rest deleted - not relevant >

Am I to assume that this is not yet implemented?   If not,  then has 
anyone implemented it
by now?

Why is the SipSession.cxx file a blank?

John
