# Set phone-menu navigation

> Turn phone-menu (IVR) navigation on or off for an agent's calls.

Phone-menu navigation is an agent setting: it applies to the calls of every task in the agent. It is off by default.

When it is on and a call reaches a phone menu or a switchboard, the agent:

* Stays silent and listens to the options.
* Presses keys toward the person who can act on the call's goal: an extension, dial-by-name, the operator (0), or the closest department.
* Goes back with `*` when an option leads nowhere useful.
* Leaves one voicemail with its callback number when only a mailbox fits.

Turn it on for agents that call businesses, where menus answer most calls. Leave it off for agents that call people on their own phones.

```json theme={null}
{ "ivr_navigation": true }
```

Read the current value in `ivr_navigation` from [List agents](/docs/en/api/master-workflows/list-master-workflows).
