It is possible to share licenses over other Cloud, Hardware and Virtual PBXs in the WMS Network. Normally this scenario is used for Failover configuration. In this scenario you add UC profiles (users) only on Server PBX and then you can share the licenses enabled on Server PBX with Client PBX(s). 


  • The PBXs must belong to the same customer

  • WMS Network must be enabled between the PBXs

  • Cloud PBX can only be the Server PBX

  • All PBXs must be of Per User type
  • There must be no licenses enabled on the Client PBX

Limitations for Cloud PBXs:

  • Cloud PBX cannot be connected to Server PBX with Lifetime license
  • Cloud PBX with increased storage size cannot be connected to Server PBX

To enable WMS Network license sharing, proceed as follows:

  • Go to WMP -> Customers

  • Select your company and customer

  • Select the Client PBX -> click Edit

  • Select WMS Network License and select the Server PBX from the drop-down list

  • Click Save
