Avaya SBC does not negotiate Offer and Answer SDP for the Far End Camera Control (FECC) media application line. Offer and Answer exchange and negotiation is done end-to-end between the sender and receiver. Avaya SBC does not support mixed encryption because FECC is tied to Media Rules. Therefore, FECC is encrypted if main video is encrypted. Similarly, FECC is on RTP if the main video is on RTP. If FECC is not negotiated in Offer and Answer end-to-end, the principal video channel works without FECC.
