Where dedicated numbers win

Four use cases iovox solves out of the box.

Marketplaces & portals

One number per listing, per professional, per region. Attribution at the exact grain your customers pay for.

  • Listing-level call data in your seller portal
  • Call masking for fraud prevention and privacy
  • Lead cost calculation that stands up in conversation with sellers
Directories & local discovery

A permanent number for every advertiser. No scripts required on the advertiser's site.

  • Zero customer integration effort
  • Call attribution that works even when the advertiser's site is down
  • A reporting dashboard for every advertiser
Multi-site & franchise

Per-location, per-brand, per-campaign numbers. Routed through one global engine.

  • Roll-up dashboards by region, brand, or location
  • Intelligent routing that respects opening hours, wait times, and overflow
  • Consistent compliance and recording policy
Print & outdoor

The only way to measure a billboard, a flyer, or a magazine ad: a unique tracking number printed on each placement.

  • Per-insertion, per-region, per-publication attribution
  • Permanent numbers with stable data across the life of the campaign
  • CRM-ready call events, straight from the billboard
