Grandstream Unveils Next-Gen Telephony & Networking Innovations

As Grandstream continues to expand the boundary between telephony, networking, and unified communications, 2025 has already seen several significant announcements that are shaping the future of how enterprises connect, communicate, and manage their systems. Here’s a roundup of the latest developments and how they affect the telephony ecosystem.

Major Highlights & Product Launches

1. GCC6020 Series: Converged UC + Networking Platform

Grandstream released the GCC6020 Series, a convergence device that packs IP PBX, VPN router, next-gen firewall, and a network switch all into one platform. blog.grandstream.com

  • For small to medium businesses, this means fewer hardware silos — voice, data, and security can now be managed from the same appliance.

  • The device supports up to 50 users (expandable to 1,000 users), concurrent calls, and can integrate with existing Grandstream endpoints — routers, APs, and IP phones — under unified management via GDMS (Grandstream Device Management System). blog.grandstream.com

  • Network specs include multiple Gigabit and 2.5 Gbps ports, along with high-availability support. blog.grandstream.com

This is a bold step toward simplifying deployments and reducing the complexity of deploying separate PBX, firewall, and networking gear.

2. First Tri-Band Wi-Fi 7 Access Point — GWN7672

In July 2025, Grandstream introduced the GWN7672, the company’s first tri-band Wi-Fi 7 access point. blog.grandstream.com

  • It supports up to 11 Gbps aggregate throughput and can serve up to 384 concurrent clients. blog.grandstream.com

  • Features include multi-radio MU-MIMO (2×2×2:2), Multi-Link Operation (MLO), preamble puncturing, and advanced QoS tuned for real-time applications like voice and video. blog.grandstream.com

  • It’s designed to integrate tightly with Grandstream’s telephony and networking stack: it can be managed through GDMS or via its embedded controller, and works well for voice-over-Wi-Fi deployments. blog.grandstream.com

This AP is a signal that Wi-Fi 7 is now entering more enterprise-grade deployment scenarios, which is especially relevant for large offices, hotels, campuses, and venues with dense traffic and many simultaneous voice/video connections.

3. Layer-2 Lite Managed Switches: GWN7721 / GWN7721P

To bolster underlying network infrastructure, Grandstream launched layer-2 lite managed switches — the GWN7721 and GWN7721P models — in August 2025. blog.grandstream.com

  • Each switch offers 8 2.5 Gbps Ethernet ports plus 2 SFP+ 10 Gbps ports. blog.grandstream.com

  • The switches support VLAN, QoS, traffic prioritization, and flexible management options, making them suitable for SMBs, branch offices, and campus environments. blog.grandstream.com

This move strengthens Grandstream’s portfolio, making sure that high-speed switching hardware keeps pace with their advanced telephony and AP offerings.

4. New DECT & Carrier-Grade IP Phones

While networking expansions grab headlines, Grandstream hasn’t slowed in the telephony domain. In late 2024, they launched DP735, GRP2610(P), and GRP2611G models. blog.grandstream.com

  • DP735 is a ruggedized cordless DECT handset (IP67 rated for waterproof/dustproof), supports up to 20 SIP accounts, offers HD voice, and supports conference calling. blog.grandstream.com

  • GRP2610(P) and GRP2611G are new additions to the carrier-grade GRP series. The GRP2610 supports 2 lines/SIP accounts, while the GRP2611G supports 3 lines and includes dual Gigabit ports. They also support features like zero-touch provisioning, 5-way voice conferencing, and “noise shield” technology. blog.grandstream.com

These devices are targeted toward businesses with mass deployments, such as call centers, hospitality, and large campus environments — offering ruggedness, reliability, and ease of provisioning.

5. Intercom & Facility Access Control Devices

To support intelligent building and facility integrations, Grandstream added the GSC3574 and GSC3575 intercom / control station models. Streakwave Blog

  • These devices are Android-based, with touchscreens, dual-band Wi-Fi, Bluetooth 5.0, customizable I/O ports, and SIP support for up to 5 accounts. Streakwave Blog

  • Their design is optimized for use in smart buildings, hospitals, hotels, and education, enabling integrated communication and control from a single station. Streakwave Blog

Implications for Telephony & Unified Communications

  1. Convergence is accelerating. With GCC6020, Grandstream is signaling a shift: instead of separately managing PBX, firewall, and switching, more organizations may adopt unified devices that combine these capabilities.

  2. Wireless will be a critical component of telephony infrastructure. With Wi-Fi 7 APs and managed switches that support multi-gigabit backplanes, telephony traffic over Wi-Fi (voice + video) becomes more reliable, less constrained by bandwidth.

  3. Simplified management matters. GDMS continues to be a key enabler, centralizing device provisioning, firmware updates, monitoring, and configuration across telephony, networking, and security.

  4. Resilience, mobility, and ruggedness. The DECT phones, intercoms, and facilities devices show that Grandstream is not only targeting desk-based users but mobile, on-the-move, or harsh environments.

  5. Growth in vertical applications. The intercom/facility line and the rugged DECT phones point to use cases in hotels, manufacturing plants, campuses, healthcare — sectors that demand durable, integrated, multi-use communication + control systems.

What This Means for Our Company & Our Clients

  • We should begin evaluating how the GCC6020 fits in as a backbone option, especially in small to medium setups, remote branches, or where reducing device clutter is valued.

  • For deployments requiring heavy Wi-Fi usage and voice/video convergence (e.g. open offices, hotels, education), the GWN7672 merits testing in pilot environments.

  • Our offering for managed networks should now include more robust switching options like the GWN7721 series, to assure full-stack performance for telephony traffic.

  • In verticals like industrial, hospitality, and campus, we can promote the rugged DECT devices and intercom/facility control lines as compelling differentiators.

  • We should update our product lineups, datasheets, and promotional content to reflect these new additions; train our pre-sales and field techs on provisioning and managing the convergence solutions via GDMS.
