Voice agents that sound human. And get things done.
Callex agents hold natural conversations in Hebrew and English, understand what callers actually mean, and resolve many routine requests, 24/7. Fewer menus, less scripting, less hold music.
Real-time speech that feels human.
Sub-second responses, natural turn-taking, and graceful barge-in handling mean callers can interrupt, change their mind, and talk like they would to a person, in Hebrew or English.
- Fluent in Hebrew and English
- Under 800ms median response latency
- Interruptible, full-duplex audio
- Lifelike, expressive voices

Understands intent, not just words.
Agents track context across the whole conversation, reason over your knowledge and policies, and know exactly when a situation calls for a human.
- Multi-turn context & memory
- Grounded reasoning over your policies
- Confident, automatic escalation
Resolves the call. Not just answers it.
Agents take real action in your systems: look up accounts, update records, book appointments, and send confirmations, all within a single call.
- Acts in your backend systems
- Can close eligible tickets in one call
- Higher containment, fewer transfers

Knows its limits, and hands off cleanly.
An agent is only trustworthy if it knows when not to answer. A Callex agent escalates to a human the moment a call is better handled by a person, and the handoff carries full context.
- The caller asks for a person.
- The agent isn’t confident it understood, after trying to clarify.
- The request falls outside the agent’s defined scope.
- A sensitive or high-risk situation is detected.
- A required backend action fails or is unavailable.
- A rule you set (for example, always route certain accounts or intents to a human).
For handoffs, the agent can pass the transcript and context to your team. If no one is available, it falls back to the path you choose: a callback, a message, or your existing IVR.
Built and tested with your team.
You don’t configure Callex alone. We build your first agent around your needs, prove it works, and refine it with you before a single real caller reaches it.
Map your needs
We characterize the calls you want to handle, your policies, and what a good outcome looks like.
We build the first agent
Our team builds an initial agent against that spec, connected to your systems.
We test it against the spec
Callex validates that the agent handles the defined scenarios before you see it.
You run test calls
You place real test calls and come back with notes. We refine until it is ready for production.
