Unity License Pooling


  With one of our customer, we have two different servers of Cisco Unity, that is Version 7.x and version 4.x. These two servers are not digitally networked but they have license pooling enabled in common.

The license information in both the servers are different now, but the subscribers were created initially using the license pooling.

Do I have to upgrade the version 4.x with an engineering special patch, in order make these two servers reflect the same license pooling info ?

Please suggest.

Re: Unity License Pooling

Hi Kumar,

System Requirements

To use license pooling, Digital Networking must be configured. In addition, for Microsoft Exchange, the servers must be in the same forest. For IBM Lotus Domino, the servers share the same Domino address book.

Using License Pooling in a Digital Network That Includes Cisco Unity 4.x Servers

If you use license pooling in a Digital Network that includes Cisco Unity 4.x servers (for example, Cisco Unity 4.x servers and Cisco Unity 7.x server are Digitally Networked), you must install an Engineering Special on the Cisco Unity 4.x servers. (A separate ES is required for each version of Cisco Unity 4.x.) Refer to the documentation for the Engineering Special for installation instructions.

Engineering Specials are available at

How License Pooling Works

If total utilization across all the networked Cisco Unity servers does not exceed total licenses for the feature, the Cisco Unity server is in compliance with licensing restrictions. For example, suppose two Cisco Unity servers each have 500 licenses for subscribers. With license pooling, one of the servers can use 501 or more licenses as long as the total used by both servers does not exceed 1,000.

License pooling requires that the Cisco Unity servers share the same corporate directory, which stores the license pooling information each server publishes as an attachment to the Location object. Because the pooling information is replicated to other server locations, each Cisco Unity server has the license pooling information it needs to monitor license usage in the pool.
