Grandstream GCC6021 UC + Network Convergence Appliance, 10G SFP+, 24 PoE, IP PBX

Overview

The Grandstream GCC6021 replaces four separate boxes in a growing office, school or hotel: the internet router, the firewall, the office phone system (IP PBX) and a 24-port Power over Ethernet (PoE) switch. It is the larger model in the GCC6020 series, with 10 Gbps routing, four 10 Gbps SFP+ ports for fibre, 370 W of PoE for phones and access points and a phone system that starts at 50 users and 16 calls at once. Everything is set up and watched from one interface.

Is it right for you?

• Suits a growing office, school, hotel or multi-site business with enough phones and access points to use a 24-port PoE switch, and that wants internet, VPN, firewall and the phone system in the same box.
• The phone system starts at 50 users and 16 calls at once; licences take it to 200 users and 48 calls and beyond.
• Eight ports supply up to PoE++ (802.3bt) for high-power access points; the other 16 supply PoE/PoE+ (802.3af/at); 370 W in total.
• Supports hot standby high availability, so a second unit can take over if one fails.
• If you need fewer ports, see the GCC6020 with five PoE outputs.

Key features

• Built-in IP PBX with 50 users and 16 concurrent calls by default, upgradable by licence.
• Four 10 Gbps SFP+ ports, eight 2.5 Gbps ports and 16 Gigabit ports, all configurable as WAN or LAN (up to five WAN).
• 24 PoE outputs: 8 x IEEE 802.3af/at/bt plus 16 x 802.3af/at, 370 W budget.
• 10 Gbps routing, 9 Gbps next-generation firewall (NGFW) throughput with DPI and IPS, 1.3 Gbps IPsec VPN and 1,000,000 NAT sessions.
• Next-generation firewall with DPI (deep packet inspection), anti-virus, IDS/IPS (intrusion detection and prevention), SSL proxy, content filtering, email security and Geo-IP filtering.
• VPN: IPsec, WireGuard, OpenVPN, PPTP and L2TP.
• Manages up to 300 Grandstream GWN access points and up to 1,000 clients.
• Hot standby high availability with two HA ports and a management port, an input for a redundant power supply (54 V DC), a console port, a USB 3.0 port and a slot for an optional M.2 SSD.

What else you need

• An internet line (several can be connected for load balancing and failover).
• SIP phones or the Wave app for staff; the appliance provisions Grandstream SIP phones and accepts standard SIP phones and trunks from other makers.
• A SIP trunk or VoIP service from a provider for outside calls.
• SFP+ modules for the 10 Gbps port(s): these are bought separately.
• Only if you need more than 50 users or 16 calls: GCC-UC upgrade licences.
• Only if you want ongoing firewall signature updates: the GCC-Security service (1-year, 3-year or lifetime).
• Only if you want extra storage: an M.2 SSD.

Installation

An IT installer or phone system installer should set it up: WAN links, VLANs, firewall rules, VPN, PoE allocation and the phone system all live on this one box. It mounts in a 19 inch rack with the included rack kit, and desktop and wall placement are also listed; it measures 440 x 301.5 x 44 mm, weighs 4.2 kg (5.6 kg packed) and is rated 0 to 45 °C. The universal power adapter (54 V DC, 7.8 A, 420 W) is included, and a second input takes a 54 V DC redundant power supply. Connect high-power devices to the eight 802.3bt ports.

Software and licences

Management is through GDMS (Grandstream Device Management System) in the cloud, the GWN app, the local web UI, SSH, SNMP v1/v2c/v3 and a CLI. The IP PBX comes with 50 users and 16 concurrent calls; GCC-UC upgrade licences raise that, including the 200-user SMB pack (200 users and 48 calls), the extra 50 extensions and extra 4 calls add-ons, and the extra 100 extensions and extra 16 calls add-ons made only for GCC602x models. Firewall signature updates come with the separate GCC-Security service, sold as 1-year, 3-year and lifetime packages.

Before you buy

• SFP+ modules for the 10 Gbps ports are bought separately.
• The 370 W PoE budget is shared across all 24 ports; total the expected load.
• PBX capacity beyond 50 users and 16 calls needs GCC-UC upgrade licences; the 100-extension and 16-call add-ons are made only for GCC602x models.
• Ongoing firewall signature updates need the separate GCC-Security service.
• Redundant power needs an external 54 V DC supply.
