TeamCall® Telephony Access Platform

Multitalented platform

The TeamCall Telephony Access Platform is the heart of our middleware and the crucial link between telephone and PC. The platform monitors the telephone system and forwards incoming calls to the connected client applications. It is ideally suited for heterogeneous company networks.

With the TeamCall Telephony Access Platform, phone system functions become freely available for processing in software applications. Additionally, proven modules are available for other ranges of use.

The TeamCall Telephony Access Platform supports the majority of currently commercially available integrated components, platforms and interfaces. Open Application Program Interfaces (APIs), libraries, example programs, technical documentation and our comprehensive project experience guarantee the smooth deployment and quick availability of individual computer-telephony functions.

Open standards

We use the relevant CSTA (Computer Supported Telephony Applications) standards. Therefore the TeamCall Telephony Access Platform is compatible with any type of implementation, and independent of the existing phone system.

Harmonizing of the existing infrastructure

Our middleware provides a common interface, normalizing the behavior of different telephone systems. From the evaluation of phone system information and the event sequence, to complex scenarios, we harmonize conditions for the development of software applications.

Platform independence

Our middleware runs on your preferred operating system: Linux, macOS, or Microsoft Windows.
(up to release 3.8.20 as a 32 bit application, starting with the upcoming summer 2020 release as a 64 bit application)

Secure migration

The TeamCall Telephony Access Platform also works with interfaces of older applications. We safeguard the backward compatibility to legacy phone systems.

Supported phone systems

The TeamCall® Telephony Access Platform can communicate with compatible phone systems via LAN.

Some phone systems require special settings or optional features in order to work with TeamCall, so please contact us before making a purchase.
