Business process integration

Business process integration

Decisive improvement of business processes.

This is how we redeem the value proposition of Unified Communications (UC) from estos. This is possible by integrating communication functions into the existing IT application environment that optimally supports the workflow of users without bossing them around.

Information Management

Information Management

Convert data into information.

Effective and efficient utilization of valuable information - this is the main task of information management. We'll show you how you can make useful and valuable information from your contact data distributed in the company and prepare it for ProCall with the aid of the MetaDirectory from estos.

Cloud Services

Cloud Services

Integrate useful cloud services

We understand cloud services as Internet-based services that are provided on highly scalable platforms when needed. The existing integration of MSN route planning or Google Maps in ProCall 3.0 Enterprise was already viewed as an integration with a cloud-based service. ProCall Enterprise 5 goes one step further here. For example, web-based applications such as SaaS applications or hosted CRM, ERP or industry solutions can be integrated in the main window with individual tabs.



Save yourself hardware.

ProCall 5 Enterprise can be optimally used with virtualized systems. This is why estos was the first German company successfully certified with its UCC solution by VMware, and is now a partner of the "Technology Alliance". However, if you decide to switch to a virtual system, you can still continue to enjoy the full benefits and opportunities of estos Unified Communication and collaboration solutions.

ProCall for Mac 

With the native ProCall for Mac OS X, small and medium-sized businesses can benefit from the proven performance features of the Unified Communications bestseller ProCall Enterprise and improve their collaboration. This version includes functions such as hotkey dial, reverse search and a call journal, Instant Messaging (chat) and presence management for Mac workstations in the company and beyond the company boundaries using Federation.

ProCall Mobile

ProCall Mobile is a native smartphone and tablet app for iPhone/iPad and Android with selected Unified Communications (UC) and CTI functions.

Once logged in, you have access to the current call list on the desk phone (journal). Call planning is also integrated. You can control your mobile extension (CTI). With Remote Office, you can use the app to dial via One Number (the cell phone number is hidden, the company number is displayed) for selected TC systems and service offers. The integrated search allows a live search of all contact databases according to contact details.

CTI with smartphones and cell phones

First Party Call Control allows smartphones, such as iPhones or Android devices, as well as classic cell phones to be integrated for call control via simple Bluetooth pairing in ProCall. 

The integration means control of the telephone and the display of calls, contacts and journals. Operate your cell phone without time-consuming tapping on the display. MDM and BYOD is now no longer a problem.



Integrate telephone systems

To be able to use the full potential of ProCall Enterprise, you need a telephone system (on-site or from the cloud) that has a CTI interface which allows you to control the connected phones. The standard ideally suited for this is called CSTA. This still needs to be prepared for the Microsoft Windows world. To do this, you either get a TAPI Service Provider (TSP) from the telephone system manufacturer or can choose a professional TAPI driver-compatible middleware from estos from the  ECSTA series for common systems.

Supported operating systems

The ProCall Enterprise Server has been specifically developed for Microsoft Windows Server operating systems.

ProCall client software is available for Microsoft Windows and Apple Mac OS X (pooled functions). For this purpose, native apps with special functions for the iPhone and iPad from Apple as well as Android smartphones are available from the respective app stores. VMware and Citrix support complete the offer.

Technical requirements

For ProCall Enterprise to run smoothly, a number of conditions relating to the hardware and software used must be fulfilled. The software has a few mandatory and a wide range of optional interfaces. These are almost always based on open standards. This should make the setup and use of the software for maximum interoperability and simultaneous investment protection as easy as possible for you. 

We work closely together with leading software and hardware vendors to respond quickly if support is required. Take advantage of the free trial options and expertise of our partners to ensure that our software also works as expected in your environment.
