# The dialer: one-click calls, the live-call banner and audio settings

Call from the phone icon, a record or the Action Bar. A live banner stays with you and every call is logged.

K3X calls happen in the browser. Click the **phone icon** in the top bar, the **Call** chip on a record, or **Call** in the Action Bar on a selection. The call connects in about a second and a live-call banner stays pinned at the top while you keep working.

## Before your first call

-   **A K3X phone number.** Buy one in **Settings → Phone & Voicemail**. Voice does not need A2P 10DLC. That is an SMS requirement only.
    
-   **Microphone permission.** The first time you call, your browser asks to use the microphone. Allow it for `app.k3x.ai`. If you dismissed it, re-enable it from the browser's site settings.
    
-   **A headset.** Laptop microphones pick up keyboard noise and echo. Any USB headset or earbuds fix it.
    

## Audio settings

Click the **phone icon** in the top bar to open the dialer popover. Device settings sit at the bottom:

-   **Output**: the speaker or headset you hear the call through.
    
-   **Ringing**: where incoming calls ring.
    
-   **Microphone**: the mic you talk into.
    
-   **Calling number**: which of your K3X numbers shows as caller ID.
    

Test Output and Microphone before your first real call.

## Three ways to place a call

### From the dialer

1.  Click the **phone icon** in the top bar.
    
2.  Type a name in **Search People or type a number**, or type a number directly.
    
3.  Click **Call from +1 ...**. The button shows the number you are calling from.
    

### From a record

Open a company or person and click the **Call** chip above the timeline. If the record has several numbers, pick one.

### From the Action Bar

Tick several records in **Companies** or **People** and click **Call** in the Action Bar. K3X works through the selection one call after another, so you can call a whole Smartview in a click.

## During the call

The live-call banner stays pinned at the top of the app wherever you go. It shows who you are talking to, the timer, and **Mute** and **End**. Type notes in the banner while you talk. They are saved to the timeline the moment you hang up.

## What is logged

After hang-up the call appears on the record timeline under the **Calls** filter with its duration, outcome and the notes you typed. The recording and transcript attach to the same entry when those are enabled for your workspace. Agents that trigger on timeline events can use the call as a signal, for example to send a follow-up email or move the deal forward.

## Credits

Calls spend credits from your single pool, in the Calling category. Open your profile (avatar, top right) to see the **Credit breakdown**.

## Troubleshooting

-   **No audio.** Check **Output** in the dialer popover. The wrong speaker is the usual cause.
    
-   **They cannot hear you.** Microphone permission is denied. Click the mic icon in the address bar and allow it.
    
-   **Dropped calls.** Almost always network. K3X needs a stable connection. Flaky Wi-Fi cuts calls.
    
-   **International dialing fails.** International voice is enabled per workspace by K3X support to prevent toll fraud. Ask in the SUPPORT chat.
    
-   **Your number shows as Scam Likely.** See Why your number says Scam Likely and how to fix it.
