When IP Office uses WebLM licensing, sufficient User licenses are required as per the IP Office users configuration and not only for the maximum number of concurrently-registered users. This is consistent with WebLM licensing for IP endpoints and receptionists. IP Office requests from the WebLM server the required User licenses (for example, Power User licenses) as per the user profile of all configured users.
Note:
With WebLM licensing, IP Office does not support configuring of a large number of users with a small number of licenses to cover only a subset of the users registering at the same time. For example, configuring three users with one User license to cover only one of the three users registering at the same time. However, if you want support of this behavior, you can use a local PLDS license file instead of Centralized WebLM licensing.
