Here is a list of the main terms and areas of application that play a role at estos in connection with TSP. 

TSP

TSP

stands for TAPI service provider, also called TAPI driver.

PBX System TSP

System TSP

generally refers to the TSP of a telephone system
(is provided by the respective manufacturer. The terms of use of the manufacturer apply, on which estos has no influence.)

ECSTA

ECSTA

is a middleware developed by estos especially for certain telecommunication systems.

Client TSP – Client TAPI driver

Client TSP

  • for outgoing dialing (send command, first-party) via the dialing help from the Microsoft Windows operating system
  • for outgoing dialing via Microsoft Outlook in Microsoft terminal server environments/Citrix XenApp environments
  • included in ProCall client for Windows
Remote TSP – Remote TAPI-Treiber

Remote TSP

  • for TAPI-capable third-party applications (network-capable, dedicated network connection) e.g. CRM/ERP application
  • TAPI line display, outgoing call (dialing help), or e.g. open window for incoming calls (application dependent, must be activatable in the third application)...
  • Monitor point inbound/outbound, signaling/line monitoring
  • directly accesses the TSP that controls the telephone system (system TSP or ECSTA)
  • not suitable for Microsoft terminal server environments/Citrix XenApp environments
    (must be deactivated in ProCall client setup if necessary. Select "Do not install TAPI driver", use MultiLine TSP instead if necessary).

This functionality is not available on SIP softphone lines.

MultiLine TSP – MultiLine TAPI-Treiber

MultiLine TSP

  • provides any number of TAPI lines of the UCServer on another computer with Microsoft Windows operating system
  • Structure: Line display/line control between primary UCServer – PBX – MultiLine TSP – further (decentralized) UCServer
  • Tip: should usually be installed on the Microsoft Windows server of the primary UCServer.
  • Application areas:
    • TAPI-enabled third-party applications in Microsoft terminal server environments/Citrix XenApp environments
    • Cascading, location networking or centralization of telephony information
      Cascading with decentralized UCServers and MultiLine TSP is only necessary if the system TSP cannot be instantiated, i.e. if several telephone systems of the same type cannot be connected to one system.

This functionality is not available on SIP softphone lines.
