Duplex Connection with Manual Call Acceptance

For a duplex connection with manual call acceptance, a connection request is not automatically established if the line is free. The calling subscriber cannot speak immediately. The called subscriber must press the relevant key first to accept the call. Then, both subscribers can communicate with each other in duplex mode (they can speak and listen simultaneously).
