I see. Is this architecture such for performance reasons? Portability? Why wouldn't PJSIP just use memory allocation like all other programs do? I suppose the next step, then, is to do what you were proposing initially, which is to create a separate pool for the call data and clean it up on call termination. I'm going to dig around and see how this can be done. Do you have any experience with it?
