701 * ALICE BOB
702 * | invite --> |
703 * | |
704 * | <-- ringing |
705 * | |
706 * | <-- starting |

709 * | |
710 * | <-- MEDIA TRANS --> |
711 * | |
712 * | end --> |
713 * | |
714 * | <-- ending |
715 *
716 * Alice calls Bob by sending invite packet.
717 * Bob recvs the packet and sends an ringing packet;
718 * which notifies Alice that her invite is acknowledged.
719 * Ringing screen shown on both sides.
720 * Bob accepts the invite for a call by sending starting packet.
721 * Alice recvs the starting packet and sends the started packet to
722 * inform Bob that she recved the starting packet.
723 * Now the media transmission is established ( i.e. RTP transmission ).
724 * Alice hangs up and sends end packet.
725 * Bob recves the end packet and sends ending packet
726 * as the acknowledgement that the call is ending.
