You need only ONE license per server, no matter how many extensions or users you have.

FOP2 licensing is based on server installation, not on the number of users, extensions, or buttons. Whether you have 5 users or 500 users, you only need a single license for that server.

This means:

• ✅ One license covers unlimited users
• ✅ One license covers unlimited extensions
• ✅ One license covers unlimited buttons
• ✅ One license covers your entire PBX installation

The only exception is for multi-tenant systems where you may need additional licensing if you have more than 5 tenants on a single server.
