Hi 1>if INVITE has an offer, but the 200 reponse doesn't have an answer (there is not any 18x reponse between them) what shall I do? Can send back the ACKwithout SDP, and immediately send BYE?
2>if INVITE hasn't an offer, but the 200 reponse doesn't have an offer yet(there is not any 18x reponse between them) Can send back the ACK without SDP, and immediately send BYE with Warning: "no SDP in 200 OK responses" header? Would appreciate your response.
