TSP TAPI service provider or TAPI driver
May 2024
Here is a list of the main terms and areas of application that play a role at estos in connection with TSP.
TSP
stands for TAPI Service Provider, also called TAPI driver.
System TSP
generally refers to the TSP of a telephone system
(provided by the respective manufacturer. The terms of use of the manufacturer apply, on which estos has no influence.)
ECSTA
is a middleware developed by estos especially for certain telecommunication systems.
The solution consists of uaCSTA server for SIP phones and ECSTA for SIP phones.
They enable controlling and monitoring telephones from applications compatible with Microsoft TAPI.
uaCSTA Server for SIP phones
- uaCSTA Server for SIP Phones is a CSTA middleware for SIP telephones capable of uaCSTA.
- provides controllable telephone resources to registered clients
- functions by concept as a registrar and proxy
- the central binding element between all participating components
ECSTA for SIP phones
- As a telephony service provider (TSP), ECSTA for SIP Phones provides a TAPI conforming to standards.
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
This functionality is available on SIP softphone lines.
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
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.
