/mcp• If dwParam1 specifies LINECALLSTATE_OFFERING, dwParam2 contains details about the connected mode. This parameter uses the following LINEOFFERINGMODE_constants: LINEOFFERINGMODE_ACTIVE The call alerts at the current station (accompanied by LINEDEVSTATE_RINGING messages) and, if an application is set up to automatically answer, it answers. For TAPI versions 1.4 and later, if the call state mode is ZERO, the application assumes that the value is active (which represents the situation on a non-bridged address). The Cisco Unified TSP does not send LINEDEVSTATE_RINGING messages until the call is accepted and moves to the LINECALLSTATE_ACCEPTED state. IP_phones auto-accept calls. CTI ports and CTI route points do not auto-accept calls. Call the lineAccept() function to accept the call at these types of devices. Note • If dwParam1 specifies LINECALLSTATE_DISCONNECTED, dwParam2 contains details about the disconnect mode. This parameter uses the following LINEDISCONNECTMODE_constants: LINEDISCONNECTMODE_NORMAL This specifies a normal disconnect request by the remote party; call terminated normally. LINEDISCONNECTMODE_UNKNOWN The reason for the disconnect request remains unknown. LINEDISCONNECTMODE_REJECT The remote user rejected the call. LINEDISCONNECTMODE_BUSY The station that belongs to the remote user is busy. LINEDISCONNECTMODE_NOANSWER The station that belongs to the remote user does not answer. LINEDISCONNECTMODE_CONGESTION This message indicates that the network is congested. LINEDISCONNECTMODE_UNAVAIL The reason for the disconnect remains unavailable and cannot become known later. LINEDISCONNECTMODE_FACCMC Indicates that the FAC/CMC feature disconnected the call. LINEDISCONNECTMODE_FACCMC is returned only if the extension version that is negotiated on the line is 0x00050000 (6.0(1)) or higher. If the negotiated extension version is not at least 0x00050000, TSP sets the disconnect mode to LINEDISCONNECTMODE_UNAVAIL.
