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
