1. What is TSP ? (by Microsoft) • Purpose - A telephony service provider (TSP) is a dynamic-link library (DLL) that supports communications device control through a set of exported service functions (TSPI). A TAPI application uses standardized commands (TAPI), TAPI Service passes information to the telephony service provider, and the TSP handles the specific commands that must be exchanged with the device. - A TSP must conform to the Telephony Service Provider Interface (TSPI) to function as a service provider within the Microsoft Telephony environment. TSPI defines the external functions exposed by a telephony service provider supplied with communications equipment.
2. TSP • Telephony Service Provider (= Device Driver) • One of TAPI Components made and delivered by 3rd Party Device Vender or Switch Vender • DLL (Dynamic Linking Library) supporting a set of exported service functions (= TSPI_XXXX Function’s Body) • All telephony service providers execute in the TAPISRV process (Telephony Service) as DLL • Give Interface to Application about how to control the specific physical telephony device
Window based PC Telephony Application TAPI TAPI Service TSPI Telephony Service Provider Phone System (PBX, Key Telephone System etc.) 3. App - TAPI - TSP Relation • TAPI Application interacts with TAPI Service and TSP using TAPI function. • TSP is located as a TAPI components on the Windows OS. • Tapi Service is a default service of Windows OS.
4. TSP Interfaces • TSP has two interfaces • TSPI interface to TAPI Service Side • Proprietary CTI Protocol Interface to Switch Side (as Cti Commands / Events)
5. Roles Of TSP • a Role as the Translator between TAPI Compatible Applications and the real Switch / Device. • TAPI Request Switch Side Action (thought TSPI_XXXX) • Switch Side Action Application (TAPI Event) • Has two interfaces. • To TAPI Side – TSPI_XXXX • To Switch Side – Proprietary CTI Protocol
6. Multiple TSPs on one system. • 3rd Party TSP • Samsung OpenTSP • Dialogic TSP etc • Windows Default TSPs • H323.TSP • IPConf TSP • Kernel-Mode Device Driver TSP • NDIS Proxy TSP • Remote TSP • Unimodem.TSP
7. What is OpenTSP ? • TSP Driver for Samsung Keyphone Switch • TAPI 2.x / TAPI 3.x Compatible (Legacy Telephony Driver) • Just only support line_XXXX type TAPI function. (not support phone_XXXX type function) • Can be used at All latest Windows OS Systems - Win98, Me, NT, 2000, XP, 2003 or later • All TAPI Compatible Application Vender can use this OpenTSP for its own purpose. - Samsung CTI Solutions (call, operator, ACD etc) - Tapi Compatible PIMs (Outlook, ACT, Phone Dialer) - 3rd party vender’s full CTI Solutions (ARC)
8. How to install OpenTSP • OpenTSP Installation means • Copy the Physical TSP File into your system folder (Physical TSP File : SCTSP32.TSP) • Register its information on the telephony configuration of your system • See the Install Guide of OpenTSP • Chap. 2 – 1.1 Installtion Condition / 1.2) Install Step
9. OpenTSP Configuration • By Control Panel • By OpenTSP Config Tool • Configuration Item • IP Address • Port No • Trace Mode
10. Dependency Issue • Refer to the Installation Guide of OpenTSP • Installtation Condition
11. OfficeServ Link • To support multiple CTI S/W at the same time (key role) • Keyphone system can’t support multiple CTI Connection( just 1 cti connection at 5002.) • There are many cti S/Ws that need this cti connection at the same time (Call/Operator/ OpenTSP/EaysSet/News/DataView etc) • To support License Check Feature for All CTI S/Ws
14. How to run OpenTSP • Just only By Application and TAPI Service • Application just call lineInitialize() with some parameters • TAPI Service calls TSPI_ProviderEnumDevice() and TSPI_providerInit(). • Within TSPI_providerEnumDevice(), all internal threads of OpenTSP will be executed. • Each thread has a role for processing some functions
19. How to unload OpenTSP • Close all opened lines by calling lineClose() • Application calls lineShutdown() • If there is no application using OpenTSP, TAPI Service will unload the instance of OpenTSP by calling TSPI_lineShutdown(). • During processing TSPI_lineShutdown(), OpenTSP will close the current TCP / IP Connection and kill all internal threads • “Unload” means the instance of TSP (as DLL) is removed from the memory area of TAPI Service
21. OpenTSP Function List • Basic Telephony Service - Make / Answer / Drop Calls • Supplementary Telephpny Service - Hold / Transfer / Redirect / Conference etc • Extended Telephony Service - proprietary services • See P.71 of the OpenTSP Driver User Guide and Supported Function List

23. Operation Description • 1) lineMakeCall : The Tapi Sampler uses the lineMakeCall TAPI function to press Extension 2002 for making a call. • 2) TSPI_lineMakeCall : The TAPI service calls the TSPI_lineMakeCall function to the OpenTSP driver after being asked to process the TAPI function. • 3) The OpenTSP driver creates the command that can be processed by the key telephone system and forwards it to the OfficeServ Link program in order to perform the functions requested by the TAPI service. • 4) The OfficeServ Link forwards the command received from each OpenTSP driver to the key telephone system of Samsung. • 5) The key telephone system interprets the forwarded command to make a call from Extension 2001 to Extension 2002. • 6) The key telephone system forwards the extension processing results to the OfficeServ Link. • 7) The OfficeServ Link forwards the extension processing results received from the key telephone system to the OpenTSP driver. • 8) The OpenTSP driver converts the event for the processing results into the form that can be processed by the TAPI service and forwards the event to the TAPI service. • 9) The TAPI service forwards the results for TAPI function processing to the Tapi Sampler through the TAPI service. • Once the steps above are completed, the Tapi Sampler offers the call processing results to users through an internal processing module.
