Hold Callers in LineNot on a Busy Tone
When every agent is on a call, Calilio Call Queue keeps your callers on the line with music or a custom announcement, then connects each one to the next available agent.
- Callers wait in line instead of hearing a busy tone or getting cut off.
- Hold music, custom announcements and queue position updates.
- Set a queue limit and a maximum wait time, with a fallback if no one answers.

Busy agents should not mean lost customers
Without a waiting line, a busy team means busy tones, dropped calls and customers who call a competitor instead.
Without a call queue
What callers experience today- Callers hear a busy tone when agents are on calls.
- Calls can disconnect automatically.
- Customers keep calling back, and important leads are lost.
- Missed-call rates climb and your team feels overloaded.

- Upload hold music or promotional audio, or record a message.
- Greetings of up to 200 characters, generated as audio in one click.

- One toggle turns queue position announcements on.
- Set the maximum number of callers allowed to wait.
- Choose what happens to the next caller when the queue is full.

A call queue holds incoming callers in a waiting line when all your agents are busy. Callers hear music or an announcement and are connected to the next available agent, in the order they called.
You choose. Type a greeting and let Calilio generate the audio, upload your own hold music or promotional audio, or record a message. You can also turn on queue position announcements.
You set the limit. When the number of waiting callers reaches it, you decide what happens next: dismiss the call, transfer it to another number or let the caller record a voicemail.
Set a maximum wait time from 1 to 60 minutes. When it runs out, the unanswered option applies. You can dismiss the call, transfer it to a number or record a voicemail.
