Overview

The DGW100 digital VoIP gateway (DGW100) provides signaling and media conversion between VoIP and ISDN networks. A typical application is to support enterprise PBX upgrades to IP when the WAN access is ISDN. The DGW100 supports 1/2/4 T1/E1 ports and up to 512 SIP trunks, to meet the requirement of large and medium-sized enterprises for VoIP services.

Product Description

1. High Performance

The TI ‘C5509 DSPs provide powerful voice processing capabilities. The  DSP daughter card’s 6000 MIPS processing capability enables the DGW100 to provide voice signal processing (G.711, G.729A, and G.723.1), echo cancellation, and T.38 fax relay under full load conditions (120 calls).

2. High Security

To ensure security, the DGW100 supports SSH and HTTPS for remote access, and provides functions including signaling and media stream encryption, automatic password strength test, brute-force password cracking prevention, cipher text data storage, access whitelist, and system log backup.

3. High Reliability

The DGW100 provides high availability features including 1+1 redundancy of Ethernet ports and AC/DC power supplies (optional), and SIP registration failover.

4. Remote Management and Maintainability

The Redstone Cloud client inside the DGW100 allows the DGW100 located behind an enterprise NAT or firewall to be accessed across Internet securely. Real-time monitoring, alarm notification, remote packet capture and software upgrades can be performed with the Redstone or third-party Remote Device Management Systems with TR-069 or SNMP protocol.

5. Comprehensive Feature Set

As an intelligent gateway running on an embedded Linux operating system, the DGW100 supports an advanced feature set such as number transformation for calling/called party, automatic routing, RADIUS billing  interface, 2nd-stage dialing tone and ring-back tone, auto dialing, DTMF detection, call-progress analysis, and RTP proxy for NAT/firewall traversal.
