An SMS gateway that supports both SMPP and HTTP API gives a messaging operation a choice that most software platforms do not: how the application talks to the hardware. SMPP is the telecom-grade protocol used by operators and high-volume platforms; HTTP API is the web-friendly interface for CRMs and internal tools. Choosing between them — … Read more

An enterprise voice gateway solution is more than a gateway purchase: it is the voice layer of the enterprise network — the trunks, numbers, routing, and monitoring that carry the organization’s telephony. A solution is designed, not assembled, and the design starts with the enterprise’s call patterns rather than the hardware catalog. This article covers … Read more

A 4G SMS modem pool uses LTE-capable modems for its lines, which changes the conversation from port counts and SIM slots to network generation and compatibility. The 4G modem connects to modern mobile networks, and for an operation buying hardware today, the network generation is a compatibility decision as much as a performance one. This … Read more

A SIM based proxy gateway is a network appliance that routes traffic through IP addresses assigned by mobile operators. Each SIM slot creates a cellular connection with its own address, and the proxy software exposes those addresses as endpoints. The result is a pool of mobile-network IPs that applications can use for authorized testing, verification, … Read more

The TGW gateway is Telarvo’s expansion platform — a 64-port, IP-based SMS gateway designed to add capacity to an existing deployment. The multi-port question is not whether 64 ports are enough; it is how a 64-port chassis fits into a fleet that may already run several gateways. This article covers the TGW’s multi-port design and … Read more

A high capacity VoIP gateway is judged by how many calls it can carry at once and how long it can keep doing so. The two numbers that define it — concurrent call capacity and SIM inventory — are often confused, but they answer different questions. Capacity is about the peak: how many calls the … Read more

A 4 port SMS gateway is the entry point of the Telarvo SMS gateway range: four radio channels, four SIM slots, and the same SMPP and HTTP API support as the largest models. It is the hardware answer for a business that wants to own its SMS sending without buying a rack-scale appliance — and … Read more

The 32-port SMS modem pool is the point where desktop bulk messaging stops being a hobby and becomes an operation. Thirty-two modems mean 32 SIM-backed lines in one enclosure, enough for a marketing team running regular campaigns, a verification service handling OTP traffic, or a business that outgrew an 8- or 16-port pool without moving … Read more

A SIM box VoIP gateway is voice hardware that uses SIM cards as its line resource and connects to an IP telephony network over SIP. The name comes from the practice of housing many SIMs in one box; the function is to give a PBX mobile-number channels that can be managed, rotated, and monitored as … Read more

A call center VoIP gateway is the trunk that connects an agent floor to the mobile network: it carries calls between the PBX and SIM-based lines, gives the center local-number presence, and provides the channels agents need for simultaneous calls. The hardware choice follows two measurements — the concurrent call peak and the volume per … Read more
