Platform Overview

Cloud-Native Softswitch Architecture

MinCloud Switch is the central session management engine powering the Minutes Network Telecom Exchange. Unlike traditional hardware-bound switches, MinCloud Switch runs as a distributed cloud-native service that automatically scales with your traffic, self-heals on failure, and delivers consistent sub-50ms call setup times regardless of load.

Built from the ground up for the era of programmable telecoms, MinCloud Switch combines carrier-grade reliability with the agility and economics of modern cloud infrastructure.

Kubernetes-orchestrated microservice architecture
✓
Horizontal auto-scaling based on real-time session load
✓
Active-active geo-redundancy across multiple continents

Protocol Support

Multi-Protocol Session Handling

MinCloud Switch natively supports all major signalling protocols, enabling seamless interoperability between modern and legacy carrier networks.

Voice

SIP (Session Initiation Protocol)

Full SIP RFC 3261 compliance with extensive support for SIP extensions. UDP, TCP, TLS, and WebSocket transports. SIP-I, SIP-T, and SIP trunking with custom header manipulation and REFER handling.

Primary Protocol
icon

H.323

Complete H.323 v7 stack for legacy carrier interconnection. Gatekeeper functionality, H.245 tunnelling, fast start, and early media support. Enables migration paths for carriers transitioning from H.323 to SIP without disrupting existing traffic.

Legacy Support
Data

ISUP / SIGTRAN

SS7/ISUP signalling over SIGTRAN (M2UA/M3UA) for PSTN interconnection. Full IAM, ACM, ANM, and REL message handling with custom parameter mapping. Bridges traditional TDM networks to the IP domain seamlessly.

PSTN Bridge
Core Engine

Enterprise-Grade Session Handling

At its core, MinCloud Switch is a massively parallel session state machine engineered to handle millions of simultaneous calls. Each session is individually tracked with full state persistence, enabling graceful failover without call drops, real-time mid-call modifications, and comprehensive CDR generation.

✓
Distributed session state with sub-millisecond replication
✓
Mid-call re-INVITE, call transfer, and forking support
✓
In-dialog session timers with configurable refresh intervals
✓
Graceful session draining for maintenance windows
✓
Real-time session count, duration, and quality metrics via API
Traffic Intelligence

Real-Time Traffic Management & CDR Processing

Comprehensive traffic visibility and control with real-time CDR generation, processing, and analytics.

Analytics

Real-Time Traffic Management

Monitor and control every aspect of your traffic in real time. Dynamic capacity allocation per trunk group, real-time CPS throttling, congestion detection with automatic overflow routing, and granular traffic shaping at the prefix, destination, and carrier level.

✓
Per-trunk CPS limits with burst allowances
✓
Dynamic traffic re-routing on congestion or quality degradation
✓
Blacklist/whitelist management with instant propagation
✓
Destination-level ASR/ACD thresholds with automated actions
Report

CDR Processing Pipeline

MinCloud Switch generates comprehensive CDRs for every session - ingress, egress, and intermediate hops. CDRs are streamed in real time to our processing pipeline where they are enriched, rated, correlated, and made available for billing, analytics, and dispute resolution within seconds.

✓
Real-time CDR streaming with sub-second latency
✓
Automated CDR enrichment with geo, carrier, and quality data
✓
Multi-format export: CSV, JSON, ASN.1, TAP3
✓
90-day hot storage with unlimited cold archive
Media Handling

Codec Transcoding & Media Services

Full media processing capabilities including codec transcoding, DTMF handling, media recording, and advanced SBC functionality.

icon

Codec Transcoding

On-the-fly transcoding between all major codecs: G.711 (a-law/u-law), G.729, G.722, AMR, AMR-WB, Opus, iLBC, and SILK. Hardware-accelerated transcoding ensures minimal latency and MOS impact, even at massive scale.

icon

Media Recording & Playback

Server-side media recording for compliance, quality assurance, and dispute resolution. Supports selective recording by trunk, destination, or custom rules. Recordings are encrypted at rest and accessible via secure API.

icon

DTMF Handling

Comprehensive DTMF support across all signalling modes: RFC 2833, SIP INFO, and in-band detection. Automatic DTMF interworking between different methods ensures reliable IVR interaction across heterogeneous networks.

Security & Scale

Integrated SBC & Load Balancing

MinCloud Switch includes full Session Border Controller functionality as an integrated layer - not a bolt-on. This means every session benefits from topology hiding, NAT traversal, TLS/SRTP encryption, and DoS protection without additional infrastructure or latency.

✓
Topology hiding with B2BUA architecture
✓
TLS 1.3 signalling encryption and SRTP media encryption
✓
SIP-aware firewall with rate limiting and anomaly detection
✓
Layer 4/7 load balancing across SBC and media server pools
✓
NAT traversal via STUN/TURN with ICE-lite support
// SBC security policy
sbc_policy {
  topology_hiding: true
  tls_version: "1.3"
  srtp: "mandatory"
  rate_limit: "5000 CPS"
  dos_protection: true

}
Financial Integration

Billing Integration & Real-Time Rating

MinCloud Switch integrates directly with the Minutes Network billing engine to provide real-time call rating, prepaid balance checking, credit control, and automated invoice generation. Every call is rated in real time - no batch processing delays, no billing surprises.

✓
Real-time rating with sub-millisecond rate lookup
✓
Prepaid balance management with configurable low-balance actions
✓
Multi-currency support with daily exchange rate updates
✓
Automated invoice generation and settlement workflows
✓
Instant settlement integration
