The Grandstream GCC range has become a popular choice for businesses that want to simplify their communications and strengthen network security without juggling multiple devices. By combining PBX, firewall, VPN, and connectivity in one platform, the GCC60xx-series is well suited to SMEs and growing organisations that need reliable, easy-to-manage solutions.

Why security updates matter

Cybersecurity threats don’t stand still, and neither should your systems. The GCC security update packages give businesses long-term protection by keeping firmware and features current. This reduces the risk of downtime, helps companies stay compliant with industry requirements, and avoids the cost of emergency fixes.

Available packages:

1-year security update (GS-GCC-SEC-1H)
3-year security update (GS-GCC-SEC-3H)
Lifetime security update (GS-GCC-SEC-LIFE)

With flat-rate pricing, businesses can plan ahead without worrying about hidden costs or surprise renewals.

Scalable PBX licensing

As businesses grow, so do their communication needs. The GCC makes it easy to expand user and call capacity through once-off PBX licences. Options include:

Add 4 concurrent calls (GS-GCC-UC-4-CC)
Add 50 SIP users (GS-GCC-UC-50-EXT)
SMB bundle: 50 SIP users + 12 concurrent calls (GS-GCC-UC-50-SMB)

Licences activate online and are simple to manage, so IT teams and MSPs can adjust resources quickly without changing hardware or migrating to new platforms.
