# Make and receive phone calls in Infinity3

Use the browser phone dialler to call customers and handle incoming calls when your account is configured for browser calling.

#### Before you start

You’ll need an enabled phone service, access to an appropriate calling number and a working microphone and speaker or headset.

Allow app.infinity3.ai to use your microphone when your browser asks.

#### Make a call

1. Log into the Infinity3 Platform at app.infinity3.ai.
2. Open the phone icon in the top navigation.
3. Search for a contact or enter their phone number, including the country code.
4. Check the **Calling From** number and change it if another permitted number is needed.
5. Open the dialler’s audio settings and check your microphone and speaker.
6. Start the call.
7. End the call when finished and add any useful follow-up notes to the contact record.

Make a test call to a colleague’s external phone before relying on the dialler for customer calls.

#### Receive calls

Incoming calls follow the routing configured for your business number. Browser calls must be routed to the appropriate user or team.

If your browser should ring but doesn’t, ask an administrator to check the number’s incoming call configuration and your user setup.

#### Things to know

- Microphone permission and audio-device settings affect call sound.
- A reliable internet connection helps prevent interruptions.
- Call charges may apply.
- If recording is enabled, follow your business’s consent and announcement requirements.

If calling fails, tell Infinity3 whether the issue affects incoming calls, outgoing calls or audio.
