16-Channel GSM/3G/4G VoIP Gateway | DCNET INDIA

In the era of smart business communication, having a robust and cost-effective telephony solution is essential. A 16-channel GSM VoIP Gateway is the ideal tool for businesses looking to bridge the gap between traditional mobile networks and modern VoIP systems.

Whether you're managing a call center, running a voice broadcasting campaign, or simply looking to optimize your telecom costs, a 16-port GSM VoIP Gateway offers unmatched flexibility, scalability, and performance. This device is especially suited for organizations that need to handle high volumes of concurrent calls over mobile networks while maintaining control and efficiency.

🔹 What Is a 16-Channel GSM VoIP Gateway?

A GSM/3G/4G VoIP Gateway is a network device that connects mobile networks (via SIM cards) to VoIP systems such as SIP servers, IP-PBXs, and cloud telephony platforms. The “16-channel” designation means the device can support up to 16 simultaneous mobile calls using 16 SIM cards—each with its own dedicated channel.

This type of gateway allows businesses to route calls through mobile networks while managing them through internet-based systems. It's a perfect combination of traditional telecom coverage and modern digital control.

🔸 Key Features of a 16-Port GSM/3G/4G VoIP Gateway

Handle up to 16 concurrent calls, ideal for medium to large call volumes. Each port supports a separate SIM card for flexible routing.

✅ 2. GSM, 3G & 4G LTE Network Support

Enjoy wide compatibility with mobile networks, ensuring call continuity and higher voice quality in both urban and remote areas.

✅ 3. SIP Protocol Compatibility

Seamlessly integrates with most VoIP platforms and IP-PBX systems using the standard SIP protocol.

✅ 4. Advanced Call Routing

✅ 5. IMEI and SIM Management

Features like IMEI auto-rotation, SIM card timing, and remote SIM management prevent SIM blocking and allow remote control of SIM cards.

✅ 6. Bulk SMS & USSD Support

In addition to voice, the gateway can send and receive bulk SMS messages, making it ideal for marketing campaigns, reminders, or automated alerts.
