ECSTA for PBX Systems

 

 

 

The ESTOS ECSTA middleware family connects proprietary phone systems with Microsoft Windows. It converts the CSTA protocol, which is made available via a phone system interface, into Microsoft TAPI, an industry standard supported by virtually all well-known applications.


ESTOS ECSTA highlights:

• Simple initial installation and maintenance
• Drivers can be multiply instantiated
• Basic and familiar telephony features
• MultiSite/multiVendor-compatible
• Supports ECMA standard CSTA phase I, II or III
• 32- and 64-bit versions available
• Compatible with MS TAPI 2.1 or higher
• Recommended by leading manufacturers


Connecting telecommunications and IT
ESTOS ECSTA middleware enables communication between phone systems and IT infrastructure allowing connected phones to be used for computer-aided applications such as contact center, Unified Communications as well as CRM and ERP systems. The middleware lets the application control and monitor the phones via a central server. A Microsoft Telephony Application Programming Interface- (TAPI-) compatible driver provides call control functions like start call, call back, call waiting, conference or call forwarding. The ESTOS ECSTA family offers a future-proof connection for business phone systems with TAPI-compatible applications.

The telecommunication world
All supported PBX systems including Siemens, Alcatel-Lucent, Aastra, Nortel and Telekom, as well as snom SIP phones, are connected seamlessly via S0, USB or Ethernet through the computer telephony interface- (CTI-) link to a Windows computer where the ESTOS ECSTA driver is installed. The middleware communicates with the PBX via the ECMA-standardized Computer Supported Telecommunications Applications (CSTA) protocol.

The IT world
IT infrastructure is integrated through the Microsoft TAPI standard (MS TAPI 2.1 or higher). The ESTOS middleware is a simple-to-set-up, highly scalable, multiply instantiated driver with a wide variety of configuration options, such as phone number formatting, to adapt to different application scenarios.  It makes phone numbers and status information from all extensions available for the IT infrastructure in real time. The transparent implementation of features allows deep and powerful integration into a large number of applications, regardless of whether they are telephony-oriented CTI, call and contact center solutions, or common business applications such as well-known CRM and ERP systems or vertical market solutions.
