Advanced
Performance, Security, and Reliability
The 14IP 2 Port T1/E1 Digital VoIP Gateway offers high performance, security, and reliability. It features a high-performance DSP chip for voice signal processing, security measures like SSH and HTTPS, and reliability features such as Ethernet port redundancy and SIP registration failover. Operating on embedded Linux, it includes various features for telephony integration like number transformation and automatic routing.
High Performance
The 14IP 2 Port T1/E1 Gateway uses a special-purpose high-performance speech processing DSP chip.The DSP daughter cardโs 6000 MIPS processing capability enables the gateway to provide voice signal processing, echo cancellation, and T.38 fax relay.
High Security
To ensure security, the 14IP 2 Port T1/E1 Gateway 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, network access whitelist, and system log backup.
High Reliability
The 14IP 2 Port T1/E1 Gateway provides high availability features including 1+1 redundancy of Ethernet ports and AC/DC power supplies (optional), and SIP registration failover.
Comprehensive Feature Set
As an intelligent gateway running on an embedded Linux operating system, the 14IP 2 Port T1/E1 Gateway 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.
