Imagine replacing four separate network and communication devices with one powerful appliance. The Grandstream GCC6020 Convergence Solution combines a high-performance VPN router, enterprise-grade next-gen firewall, scalable IP PBX, and PoE switch into a single compact unit—designed specifically for small and medium businesses that want simpler infrastructure without sacrificing capability or security. The Telecom Spot Take For our customers in small and medium businesses who want to simplify their network while adding modern communications and strong security, the GCC6020 offers a practical all-in-one path forward. By consolidating routing, firewall, PBX, and PoE switching into one metal unit with solid performance numbers (6 Gbps NGFW throughput and 1.3 Gbps IPsec VPN), it reduces hardware footprint, power consumption, and the number of management interfaces your team has to monitor. The default 50-user / 16-call PBX capacity fits many growing teams, and the upgrade path through Grandstream’s GDMS plans lets you scale without replacing hardware. PoE support on the switch ports makes rolling out phones or wireless access points cleaner and faster, while multiple configurable WAN ports with load balancing and failover keep remote workers and branch connectivity reliable. The hot-standby high availability option and broad VPN protocol support add meaningful peace of mind for hybrid work setups. Key Features True All-in-One Consolidation — Combines VPN router, next-generation firewall, IP PBX, and PoE switch into one device. This reduces the number of appliances to purchase, power, cool, and manage—ideal for offices with limited rack space or IT resources. Enterprise-Grade Security Built In — Next-gen firewall with deep packet inspection (DPI), antivirus, IPS/IDS, SSL inspection, content filtering, Geo-IP enforcement, and DoS protection helps safeguard business data and voice/video traffic without requiring a separate security appliance. High-Performance Routing & Secure Remote Access — 6.5 Gbps router throughput and 1.3 Gbps IPsec VPN performance support fast internet and secure site-to-site or client-to-site connections for hybrid teams. WireGuard, OpenVPN, PPTP, and L2TP are also supported. Scalable Unified Communications — Built-in IP PBX starts with support for 50 users and 16 concurrent calls and includes rich features such as call forwarding, transfer, parking, intercom/paging, IVR, emergency calling, and built-in audio/video conferencing via the Wave app. Fast provisioning for Grandstream SIP endpoints and upgrade options for higher capacity make it easy to start small and grow. Smart PoE Switching with Voice Prioritization — Five PoE ports (IEEE 802.3af/at, up to 120W total) with dynamic power allocation simplify deployment of IP phones, cameras, or access points. Advanced QoS with VoIP prioritization helps maintain clear call quality even during heavy data traffic. Centralized, Flexible Management — Manage the GCC6020 and all connected Grandstream endpoints through the free GDMS cloud platform (zero-touch provisioning, monitoring, firmware updates, alarms), mobile app, local web UI, SSH, SNMP, or CLI—perfect for single-site or multi-location businesses. Reliable Connectivity & Uptime — Multiple WAN ports with load balancing and failover, plus hot-standby high availability support, help keep your business online. The compact metal chassis supports desktop, wall, or rack mounting.

GCC6021 vs. GCC6020The GCC6021 offers higher throughput (10 Gbps), more ports, and a much higher PoE budget (370W), making it better for larger or heavier-traffic environments. The GCC6020’s smaller size, lower power draw, and sufficient capacity for most SMBs make it the smarter, more cost-effective choice when you don’t need the extra scale. FAQ What size businesses is the Grandstream GCC6020 designed for? It is ideal for small and medium businesses that need reliable voice and video communications, secure remote access, and PoE networking but want to avoid managing multiple separate appliances. The default capacity fits teams up to roughly 50 users, with a clear upgrade path as you grow. Can the PBX capacity be increased later? Yes. The GCC6020 ships with support for 50 users and 16 concurrent calls. Higher capacity tiers (up to 200 users / 48 calls) are available as one-time upgrades through Grandstream’s GDMS plans—no hardware replacement required. Does it support remote and hybrid workers? Yes. The built-in high-performance VPN router supports IPsec, WireGuard, OpenVPN, and other protocols for secure remote access. The PBX works with softphones and the Wave app so employees can make and receive calls from anywhere with an internet connection. How is the device managed? You can manage everything through Grandstream’s free GDMS cloud platform (zero-touch provisioning, monitoring, firmware updates, and alarms), the GWN mobile app, or the local web interface. This makes it easy for internal IT teams or managed service providers to oversee single or multi-site deployments. What are the power and cabling benefits? Five PoE ports (up to 120W total) with dynamic power allocation let you power compatible IP phones, wireless access points, or cameras directly from the GCC6020. This reduces the need for separate power adapters or PoE injectors and simplifies cable runs throughout the office. Is high availability or redundancy supported? Yes. The GCC6020 supports hot-standby high availability configurations, helping maintain uptime for critical business communications and network services. Show more
