The application then sends a query to the LINECALLINFO to get a detailed Multimedia Stream information. The information is exposed as a part of the VideoStreamInfo structure in the DevSpecific part of the LineCallInfo. The structure contains the following data. typedef struct VideoStreamInfo { DWORD StreamId; DWORD CompressionType; // MEDIAPAYLOAD DWORD BitRate; DWORD MediaMode; DWORD bKeyInfoPresent; //ipv6 DWORD RxRTPDestinationV6Offset; DWORD RxRTPDestinationV6Size; DWORD RxRTPDestinationV4; DWORD RxIpAddrMode; DWORD TxRTPDestinationV6Offset; DWORD TxRTPDestinationV6Size; DWORD TxRTPDestinationV4; DWORD TxIpAddrMode; MultiMediaEncryptionKeyInfo MediaEncryptionKeyInfo; } VideoStreamInfo; Value Data fields Indicates the index of the MultiMedia stream. StreamId Indicates the compression type of the video stream. CompressionType Indicates the bit rate of the video stream. BitRate Indicates the media mode of the video stream. MediaMode Indicates the packet size of the video stream. PacketSize Indicates whether Key Information is present. bKeyInfoPresent Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 328 Cisco Device-Specific Extensions LINECALLINFO
