FusionGate is a software-based GSM termination & VoIP gateway that runs on standard Android phones. Deploy a full operator-grade fleet in 30–60 minutes — no specialized hardware required.
A complete software stack that bridges your softswitch to real GSM radios — built for VoIP operators and call centers.
Calls route through the phone's real GSM radio for authentic, high-quality voice — not an emulated or transcoded shortcut.
Register over standard SIP to Asterisk, FreeSWITCH, or any standards-compliant softswitch. Drop FusionGate straight into your existing dial plan.
Human-like call pacing, intelligent SIM rotation, and natural usage patterns keep your traffic looking like real handset activity.
Runs two lines per device on supported Android handsets — Samsung Galaxy A13, A14, A15, A16, A35, A36, A53, A54, S9 and S10 — across Android 13–15 — for maximum density.
Automatic recovery, re-registration, and SIM management keep the fleet running 24/7 without constant operator babysitting.
Encrypted VPN transport and centrally managed certificates protect every device and signaling channel end to end.
Provision, monitor, and route calls across your entire device fleet from one operator console — no field visits.
A real-time operator console streams call detail records, registration health, and per-SIM usage as it happens.
One dashboard to monitor every gateway, push configuration, and orchestrate SIM rotation across all your sites.
No racks, no SIM banks, no proprietary boxes. Just phones, your softswitch, and FusionGate.
