Voice Agents
Autonomous AI workers that handle complex conversations, follow defined procedures, feed shared context, and surface outcomes to your team.
The agent sends outcomes and extracted data after every call.
Sessions are tested before and during deployment.
Interaction data is surfaced through interfaces to humans.

COMPARISON
Legacy IVR and phone systems vs an AI voice agent
An IVR forces callers through menus; an AI voice agent understands the request, resolves it, and hands off to a person with full context when needed. These are the differences that show up in day-to-day operations.
| Criteria | Legacy IVR / phone system | AI voice agent (IACall) |
|---|---|---|
| Availability | Office hours; voicemail after hours | Answers 24/7, holidays and call peaks included |
| Interaction | Rigid "press 1, press 2" menus | Natural conversation: the caller explains, the agent understands |
| Languages | Pre-recorded prompts per language, hard to maintain | Native Spanish, Catalan, Basque, Galician, English and 18+ languages in one call |
| Resolution | Only routes the call | Queries CRM/ERP, books appointments and closes the request |
| Handoff | The human starts from scratch | Handoff with a summary and full context |
| Data and improvement | Basic traffic metrics | Transcripts, call reasons and continuous script improvement |
| Cost | Fixed per line plus extra staff | Closed minute packages, no billing surprises |
