/mcp• x (ninth Bit from LSB) — SetRTPInfo (1 — Applications must set the RTP information and 0 — Applications must not set the RTP Information • yy (8 bits) — IPAddressing Mode. For dynamically-registered CTI ports or route points with Early Offer: For this notification, applications have to set the RTP information using the Existing LineDevspecific Type (CciscoLineDevSpecificSetRTPParamsForCall) with the IP and Port Information for the IPAddressing Mode reported. Applications must not set the RTP information on the Open Logical Channel notification if the application has already set the information on GetIP and Port notification (SLDSMT_RTP_GET_IP_PORT). For statically-registered CTI ports: For this notification, applications must open and reserve the port used for registration. To receive the Get IP and Port notification (SLDSMT_RTP_GET_IP_PORT), an application must set the DEVSPECIFIC_GET_IP_PORT message flag by using the lineDevSpecific SLDST_SET_STATUS_MESSAGES request. TAPI provides setRTP information in dwParam2 of OpenLogical Channel notification (LINE_DEVSPECIFIC Event with dwParam1 = SLDSMT_OPEN_LOGICAL_CHANNEL) along with the IP addressing capability using which the application must determine whether it has to set the RTP information. dwParam2 = 0x0000xxyy, where: • xx — SetRTPInfo (1 — Applications must set the RTP information and 0 — Applications must not set RTP information) • yy — IPAddressing Capability. TSP Reports New Error Code (LINEERR_REGISTER_GETPORT_SUPPORT_MISMATCH) when application tries to dynamically or statically register CTI port or route point without Early Offer Support, where as the CTI port is already Registered Dynamically/Statically with Early Offer support by other applications. Media Driver Support for Early Offer For an Early Offer call on a CTI Port registered with Early Offer support, when the other party has the IP and Port information of the calling party, the other party starts transmitting the media early even before the Media Events are reported on the CTI Port (registered with Early Offer). Due to this Early Media or delay in reporting Media Reception Event to the application, Wave Driver misses initial data transmitted as the current Wave Drivers (both Legacy and Cisco New Wave Driver) supports opening of the Ports and starts reception of data only after Media Events are reported to the application. To capture the early transmitted data, the receiving port needs to be opened after GET_IP_PORT Event and Buffer Incoming Data. Current supported APIs for opening a port in New Wave Driver and Legacy Wave Driver requires CODEC and other supported information (DSCP, SRTP Information, and Silence Type). But in the Early Offer case, this information is not available at GET_IP_PORT event and needs to add new API’s to open the Port, start buffering, and then Update the endpoint with other media endpoint related information (CODEC, DSCP, SRTP Information, and Silence Type). The following API’s have been added to the New Wave Driver to capture Early Media for Early Offer Call: • EpStreamOpen()—Opens the Port and Starts Buffering Incoming Data. • EpUpdateById()—Updates the Media endpoint Data Information (CODEC, DSCP, SRTP Information, and Silence Type).
