Flexible License Distribution Supported

The licensing toolkit has been extended to support flexible license distribution allowing for a more efficient use of licenses. The change applies to the use of floating licenses via a license server only. There are no functional changes in the use of node-bound licenses.

The licenses stored on a shared license store are dynamically re-distributed at runtime based on the actual usage. There is no need to pre-allocate a fixed number of licenses on initial loading of UniMRCP Server instances.

The extended licensing toolkit has been incorporated in all the UniMRCP commercial plugins as follows.


The binary packages are currently available for the following distributions:

  • Red Hat / CentOS 7
  • Red Hat / CentOS 8
  • Ubuntu 18.04 LTS
  • Ubuntu 20.04 LTS
UMS Versions

The binary packages are available for the following UMS versions:

  • 1.7.0
