Update status

Marc 2024

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
(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.

ECSTA for SIP Phones

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 – 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

This functionality is available on SIP softphone lines.

Remote TSP – Remote TAPI driver

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 driver

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.
