Test it

Key points

During your hours, your team rings first. If nobody answers, the agent takes the message.
When you are closed, the agent answers right away.
The agent never promises a callback time: it says the team will call back as soon as you open.

Not working?

Callizy shows “This number is already used by agent “…”.”

Another agent already answers on this number. Choose another number, or disconnect the other agent.

Callizy shows “This agent is disabled. Enable it first.”

Turn the agent back on from its card, then click Connect again.

The agent also answers during the day

Check your hours on the number’s page: Always closed makes the agent answer all the time.
Does the number have its own hours? Look at the Own hours for this number switch.
During your hours, the agent also takes the call when nobody picks up in time.

The alert doesn’t arrive

Did you click Update, at the top of the agent? Without it, nothing is saved.
Check the Number that receives the message in Alert you.

Frequently asked questions

I already have an agent: can it answer only in the evening?

Yes. On its card, Connect, then Outside opening hours. The After hours template is only offered when you create an agent.

What about holidays or a vacation?

Callizy has no holiday calendar. That day, switch your hours to Always closed, then back to Custom hours when you return.

What does the agent say when you are closed?

It asks for the first name, last name, callback number and reason for the call. If the caller mentions an emergency, a breakage, an outage or a danger, it asks what is happening and says the person in charge will be notified as soon as the call ends.

Does it use AI minutes?

Yes, every call the agent answers: see Understand AI minutes and the Receptionist plans.
