Note In these scenarios, no RTP packets or RTCP packets are received for a call.
- For a call that is on hold, the direction attribute is inactive from the perspective of both the Mediation Server and CCM. In this case, CCM does not send any RTP packets or RTCP packets. Existing Mediation Server code ignored the media time-out. Therefore, the call is not dropped.
- A CCM user joins in an Office Communications Server 2007 R2 conference and then mutes the telephone. Additionally, the direction attribute for the Mediation Server for the interaction with CCM is sendonly. Also, the direction attribute for the telephone is recvonly. In this case, CCM does not send any RTP packets or RTCP packets when the telephone is muted. Therefore, the call is dropped after 30 seconds.
- An Office Communicator user calls a CCM user who is configured to use Cisco Unity voice mail. When the call is connected to Cisco Unity, the call obtains the original media packets from Cisco Unity. The Office Communicator user is then prompted to leave a voice mail message. However, Cisco Unity does not send any RTP packets or RTCP packets when the Office Communicator user leaves a message. Therefore, a media time-out occurs after 30 seconds and the call is disconnected. After this occurs, the Office Communicator user cannot leave voice mail.
Note By default, the Mediation Server is installed in the following location on drive C:
<?xml version="1.0" encoding="utf-8" ?>
<add key="GatewayIgnoreMediaTimeout" value="True" />
