OptiCaller is an application for Mobile PBX with unique call optimization. It allows the user to make calls in a flexible, and above all, more cost-effective manner (average 40-95% cost savings). OptiCaller also makes it easy to manage PBX functions, e.g. call diversions and presence status, directly from the mobile phone.

The architecture is operator independent, which means that the application works regardless of mobile operator. The application has very flexible configuration options and is adaptable to suite the majority of PBX systems on the market. Configuration and deployment of clients (OTA) is easily handled by a powerful provisioning system.

OptiCaller always takes control over how each call is connected and is thus giving the user the opportunity to call in the most cost efficient way.
The call can be connected in three different ways
* Direct Call - A normal call in the cellular network.
* Call Through - Calling through the PBX.
* Call Back - Receive a call back from the PBX.
The call method can either be predefined or decided at each call with our Always Ask functionality. It is also possible to create rules that control the call method.

With OptiCaller it is easy to set your presence status using a user friendly graphical interface. In addition to handling presence it is also possible to access other switching features such as setting call forwarding and signing in or out of groups etc.

In addition to mobile PBX features the OptiCaller client can also be used with centrex systems and to simplify the usage of a calling card service.
OptiCaller is compatible with systems from: 2N, Aastra, Asterisk, Avaya, Cisco, Ericsson, innovaphone, LG-Ericsson, Nortel, Panasonic, Siemens and many more.
