Description

The D-Link DVG-6004G Series GSM/CDMA VoIP Gateway is a versatile and high-performance device designed to integrate GSM/CDMA mobile networks with Voice over IP (VoIP) systems. This gateway provides a seamless solution for businesses to connect their traditional GSM/CDMA mobile lines to a VoIP network, making it easier to leverage the benefits of both technologies. By incorporating GSM or CDMA mobile services into an enterprise VoIP system, the DVG-6004G series allows businesses to optimize voice communication costs, particularly for long-distance or international calls.

Key Features and Benefits:

1. GSM/CDMA Integration

  • GSM/CDMA Mobile Network Support: The DVG-6004G series supports GSM and CDMA networks, enabling businesses to integrate their existing mobile phone infrastructure with a VoIP network. It allows the use of mobile SIM cards, providing businesses the ability to connect mobile lines directly to their VoIP system.
  • 4 GSM/CDMA Ports (DVG-6004G): The gateway model features 4 GSM/CDMA ports, allowing businesses to connect up to four SIM cards simultaneously. This enables businesses to manage multiple mobile lines and make simultaneous calls over GSM/CDMA networks.

2. Cost Optimization

  • Least Cost Routing (LCR): The device includes a Least Cost Routing (LCR) feature that automatically selects the most cost-effective route for each call based on real-time factors like destination and call duration. This helps businesses save on telecommunication costs by routing calls through the cheapest available option, whether it’s via GSM/CDMA or VoIP.
  • International Call Savings: The integration of GSM/CDMA networks into a VoIP system provides an opportunity for businesses to significantly reduce international calling costs by leveraging mobile network pricing, especially for long-distance calls.

3. Advanced Call Routing and Management

  • GSM-to-VoIP and VoIP-to-GSM/CDMA Routing: The gateway supports GSM-to-VoIP and VoIP-to-GSM/CDMA call routing, allowing businesses to route calls from a VoIP network to GSM/CDMA networks and vice versa. This bi-directional support provides flexibility for businesses that need to maintain both VoIP and GSM/CDMA communication simultaneously.
  • Multiple Call Paths: Businesses can configure the gateway to route calls through various paths based on factors such as cost, time of day, or call destination. This enables a highly customizable communication setup, optimizing the performance of both GSM/CDMA and VoIP networks.

4. Voice Quality and Call Optimization

  • Echo Cancellation: The DVG-6004G series comes with echo cancellation technology, which ensures clear and crisp voice quality during calls by eliminating any echo that could degrade the user experience.
  • Voice Activity Detection (VAD): The device supports VAD, which helps reduce bandwidth usage by detecting periods of silence during calls and halting the transmission of voice data. This makes voice calls more efficient and improves network resource utilization.
  • Jitter Buffer: The jitter buffer helps maintain consistent call quality by compensating for variations in packet arrival times, ensuring that voice calls remain stable and free of disruptions, even under network conditions that may experience jitter.

5. Security Features

  • SIP Encryption: The gateway supports SIP encryption, such as TLS and SRTP, to ensure secure transmission of both signaling and voice data. This helps protect sensitive business communications from eavesdropping or tampering.
  • Firewall Protection: The device includes built-in firewall protection to prevent unauthorized access and secure the network against potential security threats. This makes it ideal for businesses that require both VoIP and GSM/CDMA functionality to remain secure.
  • Access Control: The DVG-6004G allows administrators to define access control policies, restricting access to the system to authorized users only.

6. Easy Configuration and Management

  • Web-Based Management Interface: The DVG-6004G features an intuitive web-based interface, which allows for easy setup, configuration, and management of the device. This makes it accessible for both technical and non-technical users to manage the system effectively.
  • Remote Management: The gateway can be managed remotely, allowing administrators to monitor and troubleshoot the device from any location. This feature is particularly useful for businesses with multiple locations or remote offices.
  • SNMP Support: The Simple Network Management Protocol (SNMP) support enables network administrators to monitor and manage the device in real-time. SNMP allows for easy tracking of device performance, call statistics, and network health.

7. Energy Efficiency

  • Power Saving Features: The DVG-6004G series is designed with energy-efficient features, ensuring low power consumption while maintaining high performance. This helps businesses reduce operating costs associated with running the gateway.
  • Power over Ethernet (PoE) Support: The device supports Power over Ethernet (PoE), simplifying installation by using a single Ethernet cable to provide both power and data connectivity. This reduces the need for additional power adapters and cables.

8. Scalability

  • Flexible and Scalable Solution: The DVG-6004G series is ideal for businesses of various sizes, from small to large enterprises. The device can handle high call volumes and can easily scale to accommodate growing communication needs as a business expands.
  • Multiple Devices: Businesses with larger communication requirements can deploy multiple DVG-6004G units to manage more GSM/CDMA connections and enhance system performance.

9. Applications and Ideal Use Cases

The D-Link DVG-6004G GSM/CDMA VoIP Gateway is perfect for businesses in various sectors, including:

  • Call Centers: It enables call centers to optimize their outgoing call routes, especially for international or mobile communications.
  • Small to Medium Businesses (SMBs): SMBs can save on telecommunication costs by integrating their GSM/CDMA mobile networks with VoIP systems.
  • International Enterprises: Businesses with a global presence can use this device to connect their international mobile phone systems to their VoIP networks, reducing international call costs.
  • Telecom Service Providers: Telecom providers can offer flexible and cost-efficient solutions for businesses needing to integrate GSM/CDMA lines into their VoIP services.

Conclusion

The D-Link DVG-6004G Series GSM/CDMA VoIP Gateway is a robust solution for businesses looking to integrate GSM/CDMA mobile lines into their VoIP system.
