In brief: Grandstream’s GWN7800 series Layer 2+ and Layer 3 network switches are designed to work alongside Grandstream VoIP phones and access points — giving SA resellers a complete network-to-handset bundle from a single vendor.
Why a VoIP Reseller Should Care About Network Switches
Every VoIP phone deployment depends on the network it runs on. Poor QoS configuration, insufficient PoE budgeting, or VLAN misconfiguration are the most common causes of bad call quality — not the PBX or the SIP trunk. For SA resellers selling Grandstream IP phones, there is a natural and profitable reason to also supply the network switch those phones plug into: you control the entire quality chain, and you earn more per deployment.
Grandstream’s GWN7800 series exists specifically for this use case — switches engineered for environments running Grandstream phones and access points, manageable from the same cloud dashboard as the rest of the Grandstream estate.
The GWN7800 Series: What Is Available
GWN7800 Standard Series (Layer 2+)
Entry-level managed switches for small-to-medium office deployments. Available in 8, 16, and 24-port configurations with 2–4 SFP uplink ports. Three models include PoE/PoE+ to power IP phones and access points without separate power adapters. Switching capacity up to 128 Gbps. Designed for networks where basic VLAN segmentation, QoS prioritisation, and port-level security are sufficient.
GWN7800 Pro Series (Layer 2++)
The higher-performance range, announced in late 2024, targets demanding enterprise and multi-floor deployments. Key upgrades over the standard series:
- Up to 48 Gigabit PoE/PoE+ ports per unit — powers an entire floor of IP phones and access points from a single switch
- Multi-gigabit uplinks — SFP+ (10 Gbps) and SFP (2.5 Gbps) built in to all Pro models
- Double the RAM and CPU of the standard series — handles larger routing tables and more simultaneous VLAN policies
- Switching capacity up to 216 Gbps
- Can connect and power up to 48 Wi-Fi access points per unit — relevant for large hospitality or campus deployments
Features That Matter for VoIP Deployments
The GWN switches include features specifically relevant to voice deployments:
- Advanced VLAN — separate voice and data traffic at the switch level; prevents data-heavy applications from saturating the voice VLAN
- QoS (Quality of Service) — prioritise voice packets over data; reduces jitter and latency for SIP traffic
- IGMP Snooping — optimises multicast traffic, which matters for VoIP paging and intercom systems
- PoE/PoE+/PoE++ — powers Grandstream GRP and GXP series phones, UCM appliances, and GWN access points from a single cable
- Port security, ARP Inspection, DoS protection — secures the network layer that VoIP depends on
- Static routing — sufficient for most SMB sites without requiring a separate Layer 3 router
Management: One Dashboard for Everything Grandstream
All GWN switches are managed via GDMS (Grandstream Device Management System) — the same cloud portal used to provision Grandstream IP phones and access points. For SA resellers managing multiple customer sites, this means a single portal to configure phones, network switches, and Wi-Fi from anywhere. The alternative is managing separate platforms from different vendors — a significant support overhead saving.
On-premises management is also available via the GWN Manager application, which is relevant for customers with strict data sovereignty requirements or sites with unreliable internet connectivity.
Is This Realistic for SA Telecoms Resellers?
The honest answer: yes, but with a caveat. Supplying network switches alongside VoIP phones makes commercial and technical sense — it increases deal size, reduces finger-pointing between “the phone reseller” and “the IT reseller” when call quality problems arise, and builds a stickier relationship with the customer. The caveat is that it requires basic networking competency: VLAN configuration, QoS policies, and PoE budgeting are not complex, but they are a step beyond pure VoIP provisioning.
The entry point is simple: any Grandstream IP phone deployment with 8 or more handsets should include a GWN PoE switch. The PoE switch powers the phones, the VLAN separates voice from data, and QoS ensures call quality. That is the minimum viable network for a Grandstream deployment — and it is a straightforward add-on to every quote.
What This Means for SA Resellers
Grandstream’s GWN7800 series gives resellers a genuinely good reason to own more of the network stack. The GDMS integration with existing Grandstream phone deployments is the key selling point — it is not a separate product line requiring a separate vendor relationship; it is an extension of the Grandstream ecosystem you are already working in. Add a PoE switch to your next Grandstream IP phone quote and see the difference in customer conversations when you can say “we manage the whole thing.”
