/mcp• 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 4.0 (0x00040000), start transmission has the following format: • hCall – The call of the Start Transmission event • 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 • 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. Start Reception Events SLDSMT_START_RECEPTION When a message is received, the RTP stream reception starts and: • dwParam2 specifies the network byte order IP address of the local machine to use. • dwParam3, specifies the high-order word that is the network byte order IP port to use. • dwParam3, specifies the low-order high-order word that is the packet size, in milliseconds, to use. When a message is received, the RTP stream reception should commence. At extension version 1, 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 start reception uses the following format: • dwParam1:from highest order bit to lowest • First 13 bits blank • G723 bit rate 2 bits Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 408 Cisco Device-Specific Extensions Start Reception Events
