Your brand, in every customer's pocket
Ship branded iOS, Android and WebRTC calling apps under your own name in weeks, not months. Your customers register over Kamailio, talk over RTPengine and watch their balance update live from CGRateS—all carrying your logo, not ours.
A softphone that's yours, not ours
Give every customer a branded OTT calling app for iOS and Android, plus a WebRTC dialer that runs in any browser. They place and receive crystal-clear calls over 3G, 4G, 5G or Wi-Fi at the rates you set—no SIM, no roaming bill, no desk phone required.
SIP credentials are auto-provisioned from the VOIXYS platform the moment you create an account, so there is nothing for the user to configure. Your logo, your colours and your name go on the app stores—VOIXYS stays invisible behind the scenes.
- Native iOS & Android apps published under your own brand
- WebRTC web dialer that runs in any modern browser, no install
- Calls over 3G/4G/5G & Wi-Fi at the rates you control
- SIP credentials auto-provisioned—zero manual setup for users
- Live balance, rates & call history pulled straight from CGRateS
What your softphone ships with
Eight capabilities that turn the VOIXYS platform into a calling app your customers actually want to keep on their home screen.
iOS & Android apps
Native softphones for iPhone and Android built on hardened SIP stacks, tuned for battery life, background calling and lossy mobile networks.
Fully white-label branding
Your logo, colours, app name, splash screen and store listing. Ship to the App Store and Google Play under your own developer account.
SIP & WebRTC calling
One identity, two transports: native SIP registration on mobile and WebRTC in the browser, both terminating on the same Kamailio front end.
OTT over data & Wi-Fi
Calls ride over the internet on any 3G, 4G, 5G or Wi-Fi connection, so your customers reach anyone, anywhere, without touching the mobile network's minutes.
Push notifications & CallKit
APNs and FCM push wake the app for incoming calls, while CallKit and ConnectionService make them ring and look exactly like a native phone call.
Auto-provisioning
Accounts created on the VOIXYS platform push SIP credentials, codecs and dial rules to the app instantly—users sign in and start calling, nothing to type.
Secure media (SRTP/TLS)
Signalling is encrypted with TLS and voice with SRTP, with RTPengine bridging and transcoding media so every leg of the call stays private end to end.
Live balance, rates & history
CGRateS feeds real-time balances, per-destination rates and itemised call history into the app, so customers always know what a call costs before they dial.
Beat local tariffs with smart callback
The same platform powers two-leg callback and DISA—so users in high-tariff regions reach the world at your rates. Eight ways to trigger a call, every leg rated in real time by CGRateS.
ANI / CLI callback
A missed call to a dedicated ANI/CLI number triggers an instant callback—no charge to the user, no app to install. The switch recognises the caller ID and rings them straight back.
Web callback widget
Drop a click-to-call widget on any site or portal. Visitors enter their number and destination, and the platform calls both ends—ideal for support and sales call-me-back flows.
SMS-triggered callback
Users text a destination number to a short or long code and the platform calls them back to bridge it. Perfect for markets where data is scarce but SMS is everywhere.
Polite & direct DISA
Choose polite DISA—the user answers, hears a dialtone or IVR and enters a destination—or direct DISA, which dials a pre-set number the moment the callback connects.
Two-leg real-time rating
CGRateS rates both call legs as they happen against the correct account, applying balances, tariffs and limits—so spend is controlled and margin is protected on every callback.
Caller authentication & PIN
Verify callers by CLI, account or a PIN entered at the DISA prompt. Stop unauthorised use, tie every callback to a wallet and keep fraudsters off your dialtone.
Schedules, retries & blacklists
Restrict callback to time windows, retry failed legs with back-off, and block abusive numbers or premium destinations with allow/deny lists per customer and route.
App & API triggers
Fire callbacks from a mobile app or your own backend over a REST API. Pass the caller, destination and account, and let VOIXYS originate, bridge and rate the call.
Built for the screen in their hand
A modern OTT stack that feels native on every device your customers carry.
