A Certified Link Between Phones & the Front Desk
If your property runs on Oracle Hospitality OPERA or OPERA Cloud, your phone system should talk to it directly. The IntelliVoice hotel PBX connects to OPERA over the industry-standard FIAS (Fidelio) interface — and to OPERA Cloud via OHIP/HTNG — so a guest's phone comes alive at check-in and locks down at check-out automatically, with no manual steps at the front desk.
Wake-up calls, message waiting lights, housekeeping and minibar status, and toll charges all flow between the PBX and OPERA in real time. The result is fewer errors, faster front-desk workflows, and every billable call posted to the right folio.
Add Voce AI for automated wake-up confirmations and after-hours guest requests, all on a FusionUC cloud PBX foundation. See the full platform on our hotel PBX and hospitality communications pages.
Your Phones to Oracle OPERA, Over FIAS
FIAS, Fidelio & OHIP
FIAS — the Fidelio Interface Application Specification — is Oracle's long-standing protocol for linking a PBX to OPERA and legacy Fidelio systems. IntelliVoice speaks FIAS over serial or IP for on-premise and hybrid OPERA deployments, and connects to OPERA Cloud through the modern OHIP (Oracle Hospitality Integration Platform) and HTNG REST interfaces.
Whether your property is on classic OPERA 5, OPERA Cloud, or migrating between the two, the same IntelliVoice hotel PBX carries every PMS-driven phone function across the transition. We handle the interface configuration, certification, and end-to-end testing.
Why Hotels Choose IntelliVoice
Faster Front Desk
No manual phone activation. Check a guest in and the room phone is live; check them out and it's restricted — automatically through OPERA.
No Lost Revenue
Every billable call and minibar charge is posted to the correct folio in OPERA in real time, so nothing slips through at checkout.
Cloud or Hybrid
Deploy fully in the cloud or as a hybrid with on-site survivability — with LTE/Starlink failover so guests are never cut off.
