# Calls are not connecting

Ringing but not answering, one-way audio and poor quality.

## Nobody's phone rings

**Check the destination.** Open **Phone Numbers** and confirm **Who answers your calls** points where you expect. See [Call forwarding & routing](/virtual-numbers/call-forwarding-and-routing.md).

**Check both availability layers.** Business hours decide whether the company is open; personal hours decide whether an individual is rung. A call inside business hours when everyone is outside their own hours has nobody to ring. Check **Settings → Business hours** and **Settings → My hours**.

**Check the device.** The member's chosen device must actually be reachable — the dashboard open for browser calling, a valid number for forwarding, a registered handset for SIP. See [Devices](/virtual-numbers/devices.md).

**Check there is a fallback.** A number with no fallback drops calls silently when the destination does not answer.

## The browser does not ring

**Microphone permission.** The most common cause. Click the padlock in the address bar and confirm microphone access is allowed for app.limecall.com.

**The dashboard must be open.** Browser calling needs an open tab.

**Try another browser.** A current Chrome or Edge is the safest test.

**Check notification permission** if you rely on the visual alert.

## One-way audio

Almost always a microphone or network problem on one side.

* Check microphone permission, and that the right input device is selected in your operating system.
* Test with a wired headset — Bluetooth devices frequently connect as an output-only profile.
* Try a wired network connection rather than wi-fi.
* Check a corporate firewall or VPN is not blocking the media path; this is common on locked-down office networks.

## Poor audio quality

* Use a wired headset. Laptop speakers with an open microphone cause echo.
* Prefer wired networking to wi-fi for browser calling.
* Close bandwidth-heavy applications — video calls, large uploads.
* If quality is poor in the browser but fine on a forwarded mobile, the problem is local, not the platform.

## Outbound calls fail

**Verify your phone number** if you have not — outbound is disabled until verification completes. See [Create your account](/start-here/create-your-account.md).

**Check credit and allowances.** Outbound is restricted when you run out. See [Usage & credits](/account/usage-and-credits.md).

**Check country permissions.** Calling to some countries is restricted by default. If calls to one country fail while others work, this is why — contact support to enable it.

**Check the caller ID.** An unverified caller ID can cause rejection at the carrier. See [Caller ID](/virtual-numbers/caller-id.md).

## Callers reach voicemail immediately

The destination is not accepting the call — a device not registered, or personal hours that have ended. Check both, then test by calling the number directly.

## Getting help

Include the call ID from **Calls**, the exact time with time zone, the numbers involved, and which side had the problem.
