# SNAPmobile Call Quality Best Practices

## Overview

A focused guide on diagnosing and improving audio quality, network stability, and overall call performance.

## Use a Strong Network Connection

SNAPmobile depends on a stable internet connection.

**Recommended connection quality:**

- Strong Wi-Fi signal when indoors
- Reliable LTE or 5G when away from Wi-Fi
- Avoid weak public Wi-Fi networks
- Avoid switching between Wi-Fi and cellular during active calls when possible

If users experience poor audio, delay, one-way audio, or dropped calls, the first thing to verify is the quality of the internet connection.

## Call Quality Best Practices

### Wi-Fi Recommendations

For best performance on Wi-Fi:

- Use a strong Wi-Fi signal.
- Avoid guest Wi-Fi networks when possible.
- Avoid public Wi-Fi for important business calls.
- Stay close to the access point when making long calls.
- Avoid moving between Wi-Fi access points during a call if the network does not support proper roaming.

Poor Wi-Fi is one of the most common causes of call quality issues.

### Cellular Recommendations

When using cellular data:

- Use LTE or 5G with strong signal.
- Avoid areas with weak reception.
- Avoid switching between Wi-Fi and cellular during an active call.
- If Wi-Fi is poor, turn off Wi-Fi and use cellular data.

### VPN

VPN applications may interfere with voice traffic.

**Recommended:**

- Disable VPN when troubleshooting SNAPmobile issues.
- If the company requires VPN, test SNAPmobile with and without VPN to confirm compatibility.
- Some VPNs may block or delay voice traffic.

### Bluetooth Audio

Bluetooth devices can sometimes cause audio routing issues.

**Recommended:**

- Use a quality headset.
- Keep the headset firmware updated, if applicable.
- Disconnect unused Bluetooth devices.
- Avoid being connected to a vehicle Bluetooth system and headset at the same time.
- If audio does not route correctly, switch audio output manually during the call.

## Troubleshooting Call Audio Issues

### If call audio is poor, check the following:

1. Is the user on weak Wi-Fi or poor cellular signal?
2. Is the user using VPN?
3. Is Bluetooth causing audio routing issues?
4. Does the issue happen on Wi-Fi, cellular, or both?
5. Does the issue happen in one location or everywhere?
6. Does the issue affect all calls or only some calls?

### If the other party cannot hear the user, check:

1. Microphone permission
2. Bluetooth audio routing
3. Muted microphone
4. Headset connection
5. Another app using the microphone
