Hello, My client has been hosting 3CX v15 on their own computer hardware on-site (computer turned PBX) via the Free license for 8 simultaneous calls and 1 trunk. There is a license expiration warning that the license will expire on the 31st December this year and the PBX will fail to stop working. Is this expiration still on course to happen and does my client need to purchase a license for further use? If they don't purchase a license in time, what will happen to the PBX? In the License page on the 3CX console, there is no date shown in the Expiry row.
