Hi! Congratulations on the new release! I've updated to the latest version but, however, still need some clarifications on the ICE processing. As far as I can understand, this is the ICE process flow: 1) Caller sends Initial Offer by calling *pjmedia_ice_create*, *pjmedia_transport_media_create* and *pjmedia_transport_encode_sdp* 2) Callee receives the Initial Offer and sends the Initial Answer by calling the same functions: *pjmedia_ice_create*, *pjmedia_transport_media_create* and *pjmedia_transport_encode_sdp* 3) Callee starts ICE connectivity checks when *on_media_update()* is called, by calling *pjmedia_transport_media_start* 4) Caller's *on_media_update()* is called and he also starts ICE connectivity checks by calling *pjmedia_transport_media_start* 5) When Caller's *on_ice_complete* is called with ice_strans_op == PJ_ICE_STRANS_OP_NEGOTIATION, he sends the Subsequent Offer, by calling *pjmedia_endpt_create_sdp*, *pjmedia_transport_encode_sdp*, *pjsip_inv_reinvite* and *pjsip_inv_send_msg* 6) Callee receives Subsequent Offer on *on_rx_offer()* and sends Subsequent Response by calling *pjmedia_endpt_create_sdp*, *pjmedia_transport_encode_sdp* and *pjsip_inv_set_sdp_answer* Is this process OK? Although the Initial Offer, Initial Answer and Subsequent Offer seem OK to me (in Subsequent Offer I can see that a=remote-candidates is being sent), I think that something must be wrong, since Subsequent Answer is being sent just like an Initial Offer
