Cut Mobile Call Costs by 70%. Bridge VoIP to GSM Seamlessly.
Multi-SIM GSM gateways with least cost routing, automatic SIM rotation, SIP trunk integration, and real-time monitoring — the complete solution for high-volume mobile call termination.
Everything You Need for Intelligent GSM Termination
From multi-SIM routing and anti-block protection to SIP integration and real-time analytics — OneQuew GSM Gateway is built for high-volume, always-on call termination.
VoIP to GSM Bridging
Seamlessly bridge VoIP calls to the GSM mobile network — route outbound calls through local SIM cards to eliminate international and long-distance call charges.
Multi-SIM Port Support
Support 1 to 32 SIM ports per gateway unit. Insert SIMs from any mobile operator and route calls through the most cost-effective network automatically.
Least Cost Routing (LCR)
Intelligent least cost routing engine automatically selects the cheapest available SIM or network path for every outbound call — maximising savings without manual intervention.
SIM Rotation & Anti-Block
Automatic SIM rotation distributes call load across multiple SIMs to prevent operator blocking and SIM suspension — keeping your gateway running 24/7.
SIP Trunk Integration
Connect your GSM Gateway directly to any SIP-based PBX, IP PBX, or call centre platform via standard SIP trunking — no proprietary hardware required.
Web-Based Management
Full gateway configuration, SIM management, routing rules, and diagnostics from a browser-based admin panel — no on-site visit needed for changes.
Real-Time Call Analytics
Live dashboards showing active calls, SIM status, call success rates, and cost savings per SIM — with detailed CDR reports for billing and audit.
100% Call Recording
Record every call passing through the gateway automatically. Recordings stored securely and accessible anytime for compliance, QA, and dispute resolution.
SNMP & Remote Monitoring
Monitor gateway health, SIM signal strength, and network status via SNMP. Receive instant alerts for SIM failures, low signal, or call drops.
Secure & Encrypted
SIP over TLS and SRTP media encryption protect all signalling and voice traffic between your PBX and the GSM gateway — enterprise-grade security.
High Call Concurrency
Handle multiple simultaneous calls per SIM port with intelligent concurrency management — no bottlenecks even during peak outbound calling hours.
Scalable Architecture
Start with a single 4-port unit and scale to multi-gateway deployments with centralised management — grow your GSM routing capacity without replacing infrastructure.
On-Premise, Data Centre & Hybrid — Your Choice
Deploy OneQuew GSM Gateway the way that fits your infrastructure — on-site hardware, co-located in a data centre, hybrid cloud, or fully remote-managed.
On-Premise Gateway
Physical GSM gateway hardware installed at your premises — full control over SIM cards, routing rules, and call data. Ideal for high-volume call centres.
Data Centre Hosted
Co-locate your GSM gateway hardware in a data centre for maximum uptime, redundant power, and low-latency connectivity to your VoIP infrastructure.
Hybrid Cloud + GSM
Combine cloud-hosted VoIP with on-premise GSM gateways — get the flexibility of cloud PBX with the cost savings of local SIM-based mobile routing.
Remote Management
Manage gateway configuration, SIM rotation, and routing rules remotely via secure web panel — no on-site engineer needed for day-to-day operations.
