Description

The D-Link DVG-5004S/DVG-5008S FXS VoIP Station Gateway is a reliable and flexible solution designed to connect traditional analog devices (such as phones, fax machines, and PBXs) to a Voice over IP (VoIP) network. It is available in two models: the DVG-5004S with 4 FXS ports and the DVG-5008S with 8 FXS ports, allowing businesses of various sizes to integrate their legacy telephony systems into modern VoIP infrastructures. These gateways provide an easy and cost-effective way to reduce communication costs while maintaining the use of existing analog phones and devices.

Key Features and Benefits:

1. FXS Ports for Analog Devices

  • 4 FXS Ports (DVG-5004S) and 8 FXS Ports (DVG-5008S): These gateways feature multiple FXS ports, enabling businesses to connect traditional analog phones, fax machines, or PBX systems to a VoIP network. This makes it possible for organizations to retain their existing telephony equipment while transitioning to VoIP services, preserving their investment in legacy hardware.
  • Analog-to-VoIP Integration: The DVG-5004S/DVG-5008S seamlessly connects analog devices to a VoIP system, providing the flexibility to leverage the benefits of VoIP, including cost savings and advanced features, without replacing existing equipment.

2. Cost-Saving VoIP Benefits

  • Voice over IP (VoIP): By supporting VoIP calls, these gateways enable businesses to make long-distance and international calls over the internet, significantly reducing telecommunication costs. VoIP technology provides more affordable pricing compared to traditional telephone lines, especially for high-volume calling environments.
  • Least Cost Routing (LCR): The DVG-5004S/DVG-5008S supports Least Cost Routing (LCR), which automatically selects the most cost-effective route for outgoing calls. This feature helps ensure businesses are always using the most economical communication route available, further reducing costs.

3. Advanced Call Management Features

  • Call Forwarding: The device supports call forwarding, which allows users to forward incoming calls to another phone number, ensuring no calls are missed.

  • Call Hold and Call Waiting: The DVG-5004S/DVG-5008S supports call hold and call waiting, allowing users to manage multiple calls simultaneously and never miss an important call.
  • Conference Calling: The gateway enables conference calling, allowing multiple participants to join a single call, enhancing collaboration in a business environment.

4. High-Quality Voice Communication

  • Echo Cancellation: The DVG-5004S/DVG-5008S comes equipped with echo cancellation technology, which eliminates unwanted echo sounds during calls, providing clear, professional-quality voice communication.
  • Voice Activity Detection (VAD): VAD detects silent periods during calls and reduces unnecessary data transmission, optimizing bandwidth and improving overall call quality.
  • Jitter Buffer: The jitter buffer compensates for network delays and packet loss, ensuring high-quality voice communication even under varying network conditions.

5. Security Features

  • SIP Encryption (TLS and SRTP): These gateways support SIP encryption, which secures signaling and voice traffic, ensuring that sensitive communication remains protected.
  • Firewall Protection: The built-in firewall helps block unauthorized access and protects the system from potential threats, enhancing security and privacy during voice communication.
  • Access Control: The device allows businesses to set access control restrictions, ensuring that only authorized users or devices can access the gateway.
