SOFTWARE UCM - UPGRADE 500Grandstream Software UCM Upgrade 500 – Extra 500 Extensions & 96 Concurrent Calls
The Software UCM Upgrade 500 package adds 500 extra extensions and 96 extra concurrent calls to an existing Software UCM installation — the large-scale step, at a better per-seat rate than stacking small packages.
This is the licence for growth you can already see coming. A consolidation of sites onto one PBX, a large legacy system being retired, a campus rollout — events measured in hundreds of seats. Because it is software on your own infrastructure, the same VM simply carries a bigger licence; capacity planning happens in your hypervisor, not in a rack.
Key features
- +500 extensions and +96 concurrent calls on the existing installation
- No reinstall, no migration — apply the licence and the capacity is there
- Better per-seat value than stacking 100-packages for large growth
Works with

- Upgrade 100 package — the stepwise option
- All IP PBX solutions
Frequently asked questions
Does applying it interrupt service?
It is a licence change on the existing installation — no reinstall and no migration. Schedule it sensibly, but this is not a rebuild.
Will the VM need more resources?
Plan for it — five hundred more extensions is real load. The pleasant part of software is that giving the PBX more CPU and memory is a hypervisor setting, not a purchase order for hardware.
