The TSAPI advanced license is intended for applications that launch calls such as predictive dialing applications or to route calls. The TSAPI advanced license is based on the following Communication Manager servers for which you need license and the size of the Communication Manager platform:

• SMALL CM 8.x and later: CM Main Max Users 1000, CM survivable Max Users 1000

• Medium CM 8.x and later: CM Main Max Users 2400

• Large CM 8.x and later: CM Hi Duplex Max Users 36000, CM Duplex Max Users 30000, CM Main/survivable Max Users 36000

The following table shows the capabilities provided with the TSAPI advanced license.

The TSAPI Advanced License requires that you license and enable the Communication Manager feature for Computer Telephony Adjunct Links.

If you have a routing application that requires additional capacity, you have the option of licensing the Increased Adjunct Route Capacity feature on Communication Manager.

Once a TSAPI advanced license is acquired on behalf of a Communication Manager server, that license remains in use till the TSAPI Service is stopped or restarted.
