IPMA is an application for managers and assistants which permits to assistants to handle managers’ calls. There are 2 types of IPMA operations:
- Proxy-line support mode
- Shared-line support mode
Proxy-line is available since Call Manager version 3.3. In this mode , calls made to managers are intercepted and redirected to an assistant or target based on the call rules. A manager in this mode can have only one associated assistant. Also the configuration of this mode is more complex as it requires the use of 2 CSS, 3 partitions, translation patterns and route points.
Shared-line is available since Call Manager version 4.0 and permits that managers and assistants share a primary line ( and DN associated). So in this mode , no special configuration is required and has also the advantage that a manager can have up to 10 assistants
