Description

The Dinstar DAG1000-4O FXO VoIP Gateway is a professional and reliable analog gateway designed to provide a seamless connection between up to four traditional analog telephone lines (PSTN lines) and a modern VoIP network. It is an ideal solution for small and medium-sized businesses and multi-location environments that need to integrate their existing landlines into a new or existing IP-PBX system.

The DAG1000-4O features 4 RJ11 FXO ports. An FXO (Foreign Exchange Office) port is used to connect to an external analog telephone line from a phone company’s central office (CO) or an FXS extension on a traditional PBX. This allows the IP-PBX to make and receive calls on these physical lines, providing a reliable trunk for both inbound and outbound call traffic. The gateway is fully compliant with the SIP protocol, ensuring high interoperability with a wide range of softswitches, IP-PBXs (like Asterisk and FreeSWITCH), and SIP-based IP telephony systems.

The device is built on a high-stability hardware platform with an embedded operating system, ensuring carrier-grade reliability. It is a fanless, compact desktop device with low power consumption, making it an excellent choice for a quiet office environment. The DAG1000-4O is packed with a comprehensive set of telephony and VoIP features, including:

• T.38 Fax over IP: Guarantees reliable fax transmission over IP networks, which is essential for businesses that still rely on fax communication.
• Superior Voice Quality: Features advanced G.168 echo cancellation (with up to 128ms tail length), an adaptive jitter buffer, and a variety of voice codecs (G.711, G.723.1, G.729A/B) to ensure crystal-clear voice communication.
• Robust Security: Supports TLS/SRTP for secure voice traffic, a built-in firewall, and various security mechanisms to protect the network.
• Flexible Management: An intuitive, web-based graphical user interface (GUI) simplifies installation and configuration. For larger-scale deployments, the gateway supports auto-provisioning via TR-069 and Dinstar’s Cloud Management System, reducing the time and effort required for setup.
• Comprehensive Call Features: Includes a full suite of standard features such as call waiting, caller ID, call forwarding, and flexible dial plans.
• Failover: Supports failover to a secondary SIP server, ensuring business continuity in the event of a primary server failure.

The Dinstar DAG1000-4O is a powerful, reliable, and cost-effective gateway that offers a clear path for businesses to modernize their communication infrastructure while preserving their existing telephone numbers and lines.
