As the company administrator you have the ability to see all numbers assigned to a site, and view whether they are free or being used by another service or user. This screen can be accessed through the “Site Management” section of the Hosted PBX system.
Numbers within this section are displayed as either a range or single number, and by selecting either “Release All” or “Release Selected” you’ll be able to release the numbers from their current use and reserve them for reallocation. If you choose to “Release Selected” you will be prompted to check the numbers required and confirm by clicking on the “Release” button.
