Protect your current physical infrastructure investments while modernizing to IP

The market for standalone VoIP gateways has declined as more businesses move to the cloud, adopt native IP hardware, and switch to SIP trunking. However, several profitable niche markets still rely heavily on these devices.

Fanvil’s entry into this market with its new GA100 series, ranging from 4 to 48 ports and targeting both FXS and FXO, allows you to capture these remaining, budget-heavy deployments. We wanted to highlight specific scenarios where using gateways is the right approach.

The Hospitality Sector (Hotels, Motels, and Cruise Ships) 

This is the single largest remaining market for high-density FXS gateways. When a 300-room hotel upgrades to a modern cloud PBX, replacing 300 perfectly functional analog guest room phones with IP phones is financially prohibitive and requires recabling the entire property with Cat6 Ethernet. In some cases, the hotel decides to keep all its legacy analog guest room phones.

They place high-density gateways, like the Fanvil GA100-32R or GA100-48R, in the server room, connecting to the hotel's existing 50-pin RJ21 amp cables. The gateway converts the analog rooms to SIP endpoints, saving the client tens of thousands of dollars.

Elevator, Emergency, and Courtesy Phones - Regulatory Niche

Safety infrastructure changes slowly because it is heavily governed by local building codes and strict compliance requirements.

Elevators, parking garage safety pillars, poolside emergency phones, and manufacturing panic buttons almost universally run on traditional analog lines.

Companies are using rugged, compact single-port or multi-port ATA gateways like the Fanvil GA10 or GA100-4 to convert these specific physical lines over to the digital SIP floor plan without altering the expensive structural emergency hardware.

PSTN Lifeline & Failover for Rural/Medical Infrastructure

In areas with unstable internet connectivity, remote clinics, warehouses, and rural businesses often require a physical "PSTN lifeline."

An FXO gateway, such as the Fanvil GA100-8T or GA100-16T, connects standard copper landlines directly to an on-site or cloud-based IP-PBX. If the primary internet or fiber connection fails, the FXO gateway automatically routes inbound and outbound emergency traffic over traditional analog lines, ensuring uninterrupted business continuity.

Legacy Fax Machines & PoS Terminals

Despite the rise of e-faxing, law firms, medical practices, financial centers, and government offices are legally mandated to use physical, standard fax machines. Credit card POS terminals at legacy merchant stations operate on the same logic.

Standard VoIP compression codecs mangle fax transmissions. By installing a low-density FXS gateway supporting T.38 Fax over IP protocol and polarity reversal, businesses can plug their physical legacy fax machines straight into the gateway for flawless transmissions over a modern IP pipe.

Historic Properties & Retrofits (2-Wire Legacy Environments) 

Historic buildings, architectural preserves, and older schools often have thick masonry walls where drilling holes to run modern Cat6 cabling is either physically impossible or legally restricted.

Gateways may no longer be at the center of every VoIP deployment, but they continue to solve critical challenges where legacy infrastructure, compliance requirements, and specialized analog devices are involved. With Fanvil's GA100 Series, partners have a flexible solution to help customers modernize at their own pace while protecting the investments they've already made.
