About Amira AI
Amira AI is an AI customer operations platform, headquartered in Saarbrücken with an office in Dubai. Its AI agents handle calls and messages across phone, WhatsApp, SMS, email, chat, RCS and Telegram. More than 200 enterprises use it, by Amira AI's own count. Its customers include Vodafone, Telekom, L'Oréal, OTTO, E.ON and Audi.
The Callback That Runs Up the Bill
Amira AI's customers put its voice agent on their phone lines. Callers can ask for a callback. Some requests came from premium-rate numbers registered to profit from the call. When Amira AI called back, a bot answered. It kept the call going as long as it could.
A premium-rate number bills the caller at a higher rate, by the minute. Amira AI's customers paid for every one of those minutes, and the bills were significant.
What We Built
Amira AI asked for a check it could run on every callback number. We built a prefix check for it. The check reads the number's range and returns a premium-rate flag. When the flag is true, Amira AI drops the number from its callback list.
The check describes the number's range. It makes no judgment about who asked for the call. The flag comes back from score.phone.validation, on every enterprise account.
What Runs on Each Number
Prefix check. Returns a premium-rate flag for the number's range, before a call is placed. It covers premium-rate ranges in 100+ countries, and coverage keeps growing.
MNP. Returns the network holding the number today, after porting.
Amira AI is expanding from voice into other channels. Two more checks describe each number for that move.
WhatsApp availability. A boolean about the number: does it accept WhatsApp.
Connectability score. phone_accessibility ranks each number from 0 to 10 by how reachable it is. -100 means undetermined, not zero.
Results
Every callback number is checked before Amira AI dials. Numbers flagged as premium-rate come off the callback list, and stay off in later dialing rounds.
In Amira AI's Words
Callback abuse was costing our customers real money. Bots on premium-rate numbers would request a callback and keep our voice agent talking as long as they could. ScoreMachine built a prefix check for us, and those numbers now come off the callback list before we dial.
