Routing intelligence

NRSA ranks every route on what it actually delivers.

Our Network Routeing Scheme Assignment engine turns live answer rates, network effectiveness, call duration and post-dial delay — weighed against the cost of the destination — into one Total Quality Indicator per supplier, per prefix.

  • Six measurement windows, from the last hour to the last four days — sudden failures and slow drift are both caught.
  • Prefix precision. A mobile range is ranked on its own traffic, not on its country's average.
  • Quality and cost decided together, through NRSA rankings that combine measurements with configured route policies.
  • ASRAnswer-seizure ratio
  • NERNetwork effectiveness
  • ACDAverage call duration
  • PDDPost-dial delay
  • RateCost of the destination

Platform

One chain from rate sheet to ledger. All of it ours.

Routing, real-time rating, invoicing and accounting run on software we built and operate — so the rate you are sent, the route you are given and the invoice you receive come from the same figures.

  1. 01
    InstantRATE
    Rates in

    Supplier rate sheets read from the mailbox, validated line by line, applied with their effective dates.

  2. 02
    NRSA
    Routing

    Every supplier on every prefix ranked by Total Quality Indicator, re-ranked as live traffic changes.

  3. 03
    Rate sheets
    Rates out

    Customer rate sheets generated and sent automatically, per service and currency, every change dated.

  4. 04
    InstantCARE
    Real-time rating

    Each call costed the moment it ends, at buy and sell rate. Credit followed both ways.

  5. 05
    Billing
    Invoicing & reconciliation

    Invoices checked against an independent count before issue; supplier invoices reconciled.

  6. 06
    Ledger
    Accounting

    Invoices posted, currencies converted at official rates, balances known on any day.

Example figures

Bilateral agreements

Swaps that stay balanced, because the books are real.

56 counterparties buy from us and sell to us. Swap arrangements are agreed separately, with defined minutes, an imbalance ceiling and settlement terms.

Quality and fraud prevention

Measured on live traffic. Reviewed against agreed limits.

Live KPIs

ASR, NER, ACD and PDD, per route and per prefix, read against the same traffic over time — not against a brochure figure.

Fraud controls

Route quality, rate and credit indicators support operational checks and the investigation of suspicious traffic.

Credit per call

Call costs and running totals support credit review in both directions, against limits agreed before traffic starts.

Swiss compliance

Commercial and technical requirements are agreed for each interconnect, with attention to applicable Swiss requirements.
