It looks like a lot of the SDP-handling in PJSUA-LIB is hidden under the covers. In our situation: - we have the remote SDP already, with a list of potential candidates - we are not using a SIP server - we want to stick to the high-level API, if possible What do we need to do to feed the SDP into PJSUA? For example, in the simple 200-line example, what would it look like to specify the remote SDP and getting ICE to choose the best one before starting a session / call?
