Your Grandstream GCC602x PBX delivers solid performance out of the box, but the standard limits of 50 users and 16 concurrent calls can quickly become a bottleneck as your team or call volume grows. The UC-200 SMB Upgrade Package removes those ceilings with a simple one-time activation that raises capacity to 200 users and 48 concurrent calls. Designed exclusively for the GCC602x series, this upgrade lets you scale your existing hardware instead of buying new equipment or planning a disruptive migration. It’s the direct, cost-effective path for small and medium businesses that need more room without sacrificing the advanced features they already rely on. Grandstream engineered this license to keep everything running smoothly while giving you permanent headroom for growth.
