-Let me explain briefly how ICE in PJNATH works, in order to understand where the memory is used. It will be good if you also read the [http://www.pjsip.org/pjnath/docs/html/index.htm PJNATH manual]. For each object mentioned below, I will also give the memory pool name format to recognize them in the memory dump output later, in square brackets. For example, "STUN session {{{[stuntp%p]}}}" means the STUN session is using memory pool which name is formatted with printf like "stuntp%p" format, e.g. "stuntp0x12345678". So here it goes.

-If ICE is enabled, each call will require one ''PJMEDIA ICE media transport'' {{{[icetp%p]}}}, which in turn creates one ''ICE stream transport'' {{{[icetp%p]}}}.
