/mcpLineCallInfo::DevSpecific indicating that the agent greeting is in progress. When the agent greeting ends, Cisco Unified TSP sends LineCallDevSpecific (SLDSMT_MEDIA_TO_BIB_ENDED) to the application and clears SendMediaToBIB bitmap in the CallAttributeType field. • When the agent greeting call arrives on the IVR port, two new bitmaps (ServerCall and BIBCall) are exposed as CallAttributeType. Cisco Unified TSP exposes LINECALLREASON_UNKNOWN as TAPI call reason when the agent greeting call arrives at IVR port, and exposes CtiReasonSendMediaToBIB in the ExtendedCallReason field. • CTI Port and Route Point do not support Agent Greeting. Application gets LINEERR_OPERATIONUNAVAIL if CCiscoLineDevSpecificStartSendMediaToBIBRequest is issued on a CTI port or Route Point. To support this feature, the application must negotiate line extension 0x000B0000 or above. Note Interface Changes See Start Send Media to BIB, on page 382, Stop Send Media to BIB, on page 383, Media to BIB Started Event, on page 417, Media to BIB Ended Event, on page 417, and Details, on page 332. Message Sequences See Agent Greeting, on page 455. Backward Compatibility This feature is backward compatible. Agent Zip Tone The Agent Zip Tone Support feature allows the TAPI applications to play tone on active calls, that is, play a tone on an agent phone after the call is answered (active state) by an agent. TAPI defines a new line devspecific CCiscoLineDevSpecificPlaytone (lineHandle, callHandle, Tone, and PlayToneDirection) message type. Applications use this message type to play the tone on a phone placed locally or remotely. Applications can play the tone on a local phone when the call is in the Accepted/Ringback state and on a remote phone when the call is in the Connected state. When the application issues CCiscoLineDevSpecificPlaytone request with tone as CTONE_ZIP and direction as local, then the Zip tone is played at the local phone and the LINE_DEVSPECIFIC event with the following parameters is reported on the local phone indicating that the tone is played: • dwParam1 = SLDSMT_CALL_TONE_CHANGED • dwParam2 = CTONE_ZIP • dwParam3 = 0(local) Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 27 Features Supported by TSP Agent Zip Tone
