Grandstream GCC6011 All-in-One Convergence Solution – IP PBX, Next-Gen Firewall, VPN Router & 10-Port Gigabit PoE Switch for Small Offices & Branch Sites

The Grandstream GCC6011 combines unified communications and networking into one compact, high-performance appliance. It integrates a capable IP PBX, enterprise-grade next-generation firewall, multi-WAN VPN router, and a 10-port Gigabit switch with PoE — all managed from a single interface. Designed for small businesses, branch offices, schools, and healthcare practices, the GCC6011 reduces the number of devices you need to purchase, power, and maintain while delivering tight integration between voice, video, and data traffic. With rack-mount capability, optional M.2 SSD storage, and powerful cloud management through GDMS, it offers a practical path to professional-grade infrastructure without unnecessary complexity. Part of Grandstream’s GCC6000 Series, the GCC6011 stands out when you need more wired ports and rack-ready deployment. The Telecom Spot Take For organizations with roughly a dozen users that want reliable voice and video communications alongside robust networking and security in a single box, the GCC6011 makes excellent sense. The extra Gigabit ports, fixed WAN configuration, rack-mount option, and support for optional M.2 SSD storage give it clear advantages over the more compact GCC6010 when you anticipate growth in connected devices or prefer rack integration. The integrated design helps prioritize voice and video traffic through smart QoS, which can reduce latency issues common when running separate systems. With a standard default capacity supports up to 24 users and 8 concurrent calls with a free firmware upgrade to version v1.0.7.54 or later (devices running earlier firmware versions are limited to 12 users and 4 concurrent calls; standard default capacity is upgradeable), comprehensive VPN options, and a next-generation firewall that includes DPI and IDS/IPS, it delivers strong out-of-the-box capabilities. The 3-year warranty and centralized GDMS cloud management add practical peace of mind for IT teams and business owners who value simplicity and long-term reliability. Key Features True all-in-one convergence — Combines VPN router, next-generation firewall, IP PBX, and network switch in one device, reducing hardware count, power consumption, cabling, and management overhead.
