SLDSMT_RECORDING_FAILED An SLDSMT_RECORDING_FAILED is generated to the application when a recording is unable to restart after being interrupted. The application must then restart the recording. The format of the parameters follows: LINE_DEVSPECIFIC hDevice -TAPI call handle dwParam1 -SLDSMT_RECORDING_FAILED (0x1C) dwParam2 -cause code for failure dwParam3 -unused Start Transmission Events SLDSMT_START_TRANSMISION When a message is received, the RTP stream transmission starts and: • dwParam2 specifies the network byte order IP address of the remote machine to which the RTP stream should be directed. • dwParam3, specifies the high-order word that is the network byte order IP port of the remote machine to which the RTP stream should be directed. • dwParam3, specifies the low-order word that is the packet size, in milliseconds, to use. The application receives these messages to signal when to start streaming RTP audio. At extension version 1.0 (0x00010000), the parameters have the following format: • dwParam1 contains the message type. • dwParam2 contains the IP address of the remote machine. • dwParam3 contains the network byte order IP port of the remote machine to which the RTP stream should be directed in the high-order word and the packet size in milliseconds in the low-order word. At extension version 2.0 (0x00020000), start transmission uses the following format: • dwParam1:from highest order bit to lowest • First two bits blank • Precedence value 3 bits • Maximum frames per packet 8 bits • G723 bit rate 2 bits • Silence suppression value 1 bit • Compression type 8 bits • Message type 8 bits • dwParam2 contains the IP address of the remote machine Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 407 Cisco Device-Specific Extensions Start Transmission Events
