General 
 

OpenScape Business TAPI 120  
OpenScape Business TAPI 120 is a first party telephony provider based on MS Windows TAPI functionality and is always deployed on client PCs. OpenScape Business TAPI 120 enables TAPI-based applications to have the control and status / presence display of telephones connected to a OpenScape Business system. To enable this, OpenScape Business TAPI 120 communicates with the system directly via LAN protocols.

OpenScape Business TAPI 120 and HiPath TAPI 120  
Considering the released operating systems a parallel installation of OpenScape Business TAPI 120 and HiPath TAPI 120 is possible. Then there are two different TAPI providers with separate licensing. That means HiPath TAPI 120 licenses are not usable for OpenScape Business TAPI 120.

Documentation  
 •   To improve readability, "telecommunications system(s)" or "communication system(s)" have been abbreviated to "system(s)" in this document.
 •   The product name OpenScape Business TAPI 120 has also been abbreviated to TAPI 120 for the same reason.
 •   All described operation sequences and dialogs refer to Windows 7. With using other released Windows versions you have to activate the functions accordingly.

Operation modes  
TAPI 120 can be connected to a OpenScape Business system with two operation modes. The basic functionality is identical, but the range of supported features varies:
 1.   Operation mode: OpenScape Business TAPI CSTA
TAPI 120 is connected via CSTA to this OpenScape Business system models:
   •  OpenScape Business with UC Booster Card
   •  OpenScape Business with UC Booster Server
   •  OpenScape Business S

 2.   Operation mode: OpenScape Business TAPI UC Smart
TAPI 120 is connected via WSI (web service interface) to a basic OpenScape Business system:
   •  OpenScape Business (without Booster Card / Booster Server)
ShowMore TAPI 120 connected to OpenScape Business (operation mode TAPI UC Smart) 
A parallel operation of TAPI 120 in both operation modes is not possible. TAPI 120 with operation mode OpenScape Business TAPI UC Smart runs only if no Booster Card / no Booster Server is installed or configured on the system.  
When migrating a OpenScape Business system to a system with Booster Card / Booster Server the UC Server parameters have to be reconfigured for every TAPI 120 user. A reinstallation of TAPI 120 is not necessary.  

Licensing of TAPI 120  
The TAPI 120 licensing is handled in the OpenScape Business. Further information is available in the OpenScape Business documentation.
Every TAPI 120 user connected to OpenScape Business requires a separate user licence (starting with the first user).  
The use of older TAPI 120 licences is not possible.  

Maximum number of TAPI 120 users  
The maximum number of TAPI 120users / maximum number of parallel TAPI 120 connections depend on the OpenScape Business system operation mode and model. You find more information about this limitations in the corresponding sales information.

CTI firewall / access control in the OpenScape Business  
The user accounts for TAPI 120 are monitored depending on the operation mode:
 •   With operation mode OpenScape Business TAPI CSTA the user licensing and the CTI firewall monitors user logins. By default CTI Firewall is activated, so a login of TAPI 120 users even with valid licenses is not possible and therefore the automatic registration of this users in the firewall is also impossible. You receive more information in the OpenScape Business documentation.
 •   With operation mode OpenScape Business TAPI UC Smart the TAPI 120 user access is controlled by both, the user licensing and the integrated user account control of UC Smart.

Supported phones / devices

Support of MULAP (multi line appearance)  
TAPI 120 directly supports basic MULAP groups, i.e. an OpenScape Business MULAP group can be used as a TAPI 120 user.
Each OpenScape Business member of a MULAP group requires a separate TAPI 120/170 user licence.  

TAPI application: Example  
The easiest way to work with TAPI 120 is to use the default Windows application Dialer. It is possible to start outgoing calls with this application. You can find more information about this application in your Windows documentation.
