RGW96 VoIP Gateway: High-Density Analog-to-SIP Conversion for Enterprise Networks
As telecom carriers worldwide accelerate PSTN shutdown timelines, enterprises with substantial analog infrastructure face critical connectivity challenges. The Redstone RGW96 VoIP Gateway addresses this transition with 96-port high-density analog-to-SIP conversion, enabling organizations to preserve existing phones, fax machines, alarm systems, and POS terminals while connecting to modern SIP trunking services.
Industry-Leading Port Density
The RGW96 supports configurations of up to 96 FXS ports (for connecting analog phones) or 96 FXO ports (for connecting PSTN lines), or mixed deployments balancing both requirements. This density exceeds most competing solutions in its class, reducing rack space requirements and simplifying cabling infrastructure in data centers and telecom closets.
Carrier-Grade Voice Quality
Built on dedicated DSP architecture, the RGW96 supports G.711, G.729, G.726, and iLBC codecs with adaptive jitter buffering, echo cancellation (128ms tail length), and packet loss concealment. The result is toll-quality voice that matches or exceeds traditional PSTN clarity, even across international SIP trunking connections.
Seamless PBX Integration
The RGW96 integrates with virtually any PBX platform—legacy TDM systems from Avaya, Nortel, and Panasonic; modern IP-PBX solutions including Redstone REX, Asterisk, and 3CX; and hosted PBX services. Multiple registration targets, flexible routing tables, and programmable dial plans ensure the gateway adapts to existing call flows rather than forcing infrastructure changes.
Advanced Security and Management
Enterprise communications security is non-negotiable. The RGW96 supports TLS transport for SIP signaling, SRTP for encrypted media streams, and VLAN tagging for network segmentation. The web-based management interface provides real-time port status, call detail records, SNMP monitoring, and automated firmware updates—reducing administrative overhead while maintaining security posture.
Proven Deployment: Federal Court of Malaysia
The Federal Court of Malaysia selected the RGW96 for their nationwide court communication modernization. The deployment connected legacy courtroom analog systems to a centralized SIP infrastructure, enabling unified dial plans across 25 locations while preserving existing courtroom recording and intercom equipment. The project completed ahead of schedule with zero disruption to court operations.
Technical Specifications
RJ21 telco connectors simplify high-density installations; dual Gigabit Ethernet ports provide network redundancy; AC/DC power options support enterprise data center standards; and rack-mountable 1U chassis optimizes infrastructure footprint. The gateway supports up to 96 concurrent G.711 calls or proportionally more with compressed codecs.
For organizations planning PSTN migration or seeking to extend analog device lifespans, the RGW96 offers unmatched density, reliability, and integration flexibility. Contact Redstone for a network assessment and migration roadmap.
