PSTN to Data Technologies | Minutes Network

Overview

The Bridge Between PSTN and the Future

The telecommunications industry is undergoing a fundamental shift from circuit-switched PSTN networks to IP-based data networks. Jingle Plugin provides the critical bridge technology that lets carriers, enterprises, and developers connect these two worlds seamlessly - without costly infrastructure replacement or service disruption.

Protocol Conversion

Real-time conversion between SIP, PSTN signalling (SS7/ISUP), and WebRTC protocols. Jingle Plugin handles the complex protocol translation transparently, so both sides of the call experience native connectivity without any awareness of the conversion happening.

WebRTC Gateway

A production-grade WebRTC gateway that enables browser and mobile app users to make and receive calls to/from the PSTN network. No plugins, no downloads, no softphones - just click-to-call functionality that works in any modern browser.

SIP-to-WebRTC

Seamless SIP-to-WebRTC and WebRTC-to-SIP conversion with full support for call control signalling, DTMF relay, call transfer, hold/resume, and conferencing. Your existing SIP infrastructure gains instant WebRTC capability without any modifications.

Mobile App Integration

Native SDKs for iOS and Android that embed PSTN calling capabilities directly into your mobile applications. Users can make and receive phone calls within your app, with call quality that matches or exceeds native dialer performance.

PSTN Breakout

Enable data-native applications to reach any phone number worldwide. Jingle Plugin routes calls from WebRTC, SIP, or data channels to the PSTN, handling codec transcoding, number formatting, and carrier routing automatically.

Quality Preservation

Advanced codec transcoding ensures HD voice quality is preserved across protocol boundaries. Our adaptive bitrate engine optimises audio quality based on network conditions, maintaining crystal-clear calls even on congested or low-bandwidth connections.

Revenue Engine

Your App Earns Revenue from Day One

Jingle Plugin is not just a calling technology - it is a passive revenue engine. Any mobile app can integrate the Jingle SDK and earn a share of wholesale voice termination revenue. International calls are routed through users' devices in the background, with full user consent. No ads, no user disruption, no UX changes - just a new revenue stream powered by the global telecom network.

Technology

How Jingle Plugin Works

Jingle Plugin operates as an intelligent media and signalling gateway that sits between PSTN and data networks, performing real-time protocol conversion, codec transcoding, and quality optimisation.

Architecture

Intelligent Gateway Architecture

Jingle Plugin uses a multi-layer architecture that separates signalling, media processing, and application logic. This design enables independent scaling of each layer, ensuring that the gateway can handle millions of concurrent sessions while maintaining sub-100ms conversion latency.

✓

Signalling layer: SIP ↔ WebRTC ↔ SS7 translation

✓

Media layer: real-time codec transcoding with <20ms overhead

✓

Application layer: routing logic, call control, and analytics

✓

Each layer scales independently for optimal resource utilisation

Carrier Network Modernisation

Carriers transitioning from TDM/PSTN to IP can use Jingle Plugin as a migration gateway. Maintain service continuity for legacy subscribers while progressively migrating traffic to data-based transport. Reduce PSTN infrastructure costs without disrupting customers.

Dual Financial Impact

One SDK, Two Revenue Impacts

The Jingle SDK's SIP capability is bidirectional. Beyond generating termination revenue, it enables your customer support team to call users directly inside your app via SIP - eliminating outbound PSTN call costs entirely. Users receive support calls within the app context, resulting in higher pickup rates and faster resolution.

✓

Inbound revenue: earn from international call termination routed through installed users

✓

Outbound savings: eliminate PSTN costs for customer support calls - they happen in-app via SIP

✓

Higher pickup rates: in-app calls are answered more often than calls from unknown numbers

✓

In various stages of integration with major app partners

✓

One SDK integration delivers two financial impacts simultaneously

Migration Path

Progressive PSTN Migration

Jingle Plugin enables a gradual, risk-free migration from PSTN to data networks. There is no need for a disruptive "big bang" switchover. Start by bridging a small percentage of traffic, validate quality metrics, and progressively increase data-based routing as confidence grows.

✓

Phase 1: Bridge - run PSTN and data in parallel with Jingle Plugin

✓

Phase 2: Migrate - progressively shift traffic from PSTN to data

✓

Phase 3: Optimise - full data network with PSTN fallback

✓

Phase 4: Complete - fully data-native with PSTN breakout only
