For LexVoice we built Karolina, an AI phone assistant for bailiff offices that answers calls, works out who is calling and why, and sends the office a ready-made note instead of a missed-call number.

LexVoice is a startup from Rzeszów that offers bailiff offices a virtual phone assistant called Karolina. In a bailiff office the phone never stops: debtors, creditors, auction bidders, banks and public institutions. Every call pulls an employee away from case files, and missed calls left nothing behind but a number with no context. LexVoice had the idea and needed a team to build the product from scratch. We built the whole system: a voice agent that holds the conversation in real time, recognises who is calling and about what, and collects the details the office needs, plus a panel where LexVoice manages offices, phone numbers and submissions. After every call the office receives an email with a structured note and a transcript. We also own the telephony integration, infrastructure and maintenance. The result: four offices in production, thousands of calls handled in the first weeks, and employees who return to cases with the context already in hand.

Challenge we faced

  • Noise, echo and dropouts on phone lines made the assistant mistake interference for the caller's speech or cut off her own sentence.
  • Case signatures (Km, Kmp, Kms, GKm) and document names sound alike over the phone, and one wrong letter routes a submission to the wrong case.
  • Every call had to reach the office exactly once, even when the caller hung up mid-sentence or one of the services along the way failed.
  • Voice models change every few weeks, and each change affects interruptions, transcription and the cost per minute differently.
  • Every office has a different PBX and different call-forwarding rules, yet all of them had to run on one system.
