In this scenario, the User Agents (UAs) are both SIP-enabled phones. What is the correct order of this basic SIP message flow?
1)The UAC initiates the session with an INVITE.
2)The UAS sends a 200 OK message indicating that the request has succeeded.
3)Media is exchanged bidirectionally.
4)The UAS sends a 100 Trying response back to the UAC
5)The UAC sends a BYE message. This is followed by a 200 OK final response message sent by the UAS.
6)The UAS sends a 180 Ringing message.
7)The UAC sends an ACK message confirming that it has received a final response to INVITE.
