hello all i have observed an issue using this parameter, which is useful in case you deactivate a node from the rtpengine sets, to let the calls to finish the negotiation. but i have tested that if a node fails down in the middle of a call, with that option activated, the kamailio gets blocked waiting until the rtpengine node is again up, to finish handling with the BYE request for instance.
