The hosted switch, on PacketExchange.

PacketExchange runs a hosted Class-4 switch for wholesale voice, with no hardware, licences or upkeep. Bring your suppliers, sign your customers and widen the spread.
  • AI Control

    Onboard customers, add suppliers, trace routing and check money owed in plain English, with approval before changes apply.

  • Everything in the plan

    Customer and supplier portals, fraud screening, invoicing and netting, with unlimited minutes switched and a maximum number of concurrent calls per plan.

  • Published plans

    Plans from $500 a month for up to 500 concurrent calls, as published on packetexchange.io. Plans cover the switch: call termination is billed separately. 30 days free, on application.

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
  • Zero-downtime rolling updates and configuration changes

Multi-protocol session handling

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

  • 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.

  • 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.

  • 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.

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

Real-time traffic management & CDR processing

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

Codec transcoding & media services

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

  • 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.

  • 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.

  • 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.

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
  nat_traversal: "STUN/TURN/ICE"
}

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

    DELETE /v2/switch/blacklist/{prefix}
  • Real-time monitoring dashboard

    A purpose-built monitoring interface that gives your NOC team complete visibility into switch health, traffic flows, and quality metrics. Customisable widgets, configurable alerting thresholds, and deep-dive drill-down capabilities for rapid troubleshooting.

High availability & geo-redundancy

Engineered for four-nines uptime with active-active deployments, automatic failover, and zero single points of failure.

  • Multi-region

    Active-active deployment across multiple global PoPs ensures traffic is served from the nearest healthy node.

  • Auto-failover

    Sub-second failover between nodes with stateful session handoff: no call drops during switchover.

  • Auto-scaling

    Kubernetes HPA scales switch instances based on CPS and session count, handling traffic spikes automatically.

  • Zero downtime

    Rolling updates, canary deployments, and graceful session draining mean upgrades happen without service interruption.
