# Mobile or Web Phone at Home over Wi-Fi

## Overview

Mobile and Web Phone allow you to stay connected from anywhere. At home, Wi-Fi quality is critical for call quality and reliability. This guide provides best practices and troubleshooting steps to ensure the best performance while working remotely.

## Best Practices for Optimal Performance Use a Stable and High-Speed Connection

- Recommended speed: 10 Mbps down / 2 Mbps up
- Prefer fiber or cable over DSL or satellite
- Avoid public Wi-Fi or mobile hotspots

## Use 5 GHz Wi-Fi Instead of 2.4 GHz

- Less interference and faster speeds
- Ideal for video/voice applications

## Prioritize Voice Traffic (QoS)

- Enable QoS on your router and prioritize VoIP traffic
- Reduces delays and dropped packets

## Keep Software & Firmware Updated

- Update the Mobile app and your browser
- Keep your router firmware current

## Close Background Applications

- Streaming, file downloads, and gaming can affect call quality

## Use Headsets

- Use a USB headset (Web) or wired/Bluetooth earphones (Mobile) for better audio

## Troubleshooting Common Issues

| **Issue** | **Cause** | **Solution** |
| --- | --- | --- |
| One-way or no audio | NAT/firewall or poor signal | Restart app/router; disable SIP ALG |
| Choppy or dropped calls | Weak signal/congestion | Move closer to router; pause other devices |
| Not registering | Permissions/firewall | Allow mic/network; check port settings |
| Calls not ringing | Battery optimization | Disable Do Not Disturb; allow background activity |
| Web Phone not loading | Browser or permissions | Use Chrome/Firefox; clear cache; allow mic access |

Using in Weak or Unstable Wi-Fi Areas

- Use Wi-Fi Extenders or Mesh Systems – Improve coverage throughout your home
- Maintain Line of Sight – Avoid barriers like walls or appliances
- Switch to Mobile Data (Mobile only) – Disable Wi-Fi temporarily if LTE/5G is more stable
- Enable Call Forwarding – Forward to your cell number as backup
- Limit Other Network Usage – Pause downloads, streaming, etc.
- Test Before Important Calls – Make a test call from your current location Pro Tip: Check Wi-Fi Signal Strength
- On iOS: Settings > Wi-Fi > Tap ⓘ → signal bars or RSSI
- On Android: Use Wi-Fi Analyzer or similar app

Signal better than -60 dBm is ideal. Below -75 dBm may result in poor call quality.

## Switching Between 5 GHz and 2.4 GHz

| **Band** | **Pros** | **Cons** | **Best Use** |
| --- | --- | --- | --- |
| 5 GHz | Faster speeds, less interference | Shorter range, poor wall penetration | Near the router, in open areas |
| 2.4 GHz | Longer range, better wall penetration | More interference, slower speeds | Far from router, through walls, larger homes |

When to Use 2.4 GHz

- Two or more rooms away from the router
- Experiencing dropped or choppy calls
- Weak signal bars on your device
- In multi-story homes or dense construction

## How to Switch Bands

Access your router settings and give each band a separate SSID (e.g., 'MyWiFi_2G' and 'MyWiFi_5G'). Connect to the 2.4 GHz network manually when farther from the router.

## Router & Network Configuration

- Disable SIP ALG – can interfere with VoIP signaling.
- Enable QoS and prioritize the device or app used for SNAP.
- Open required ports if behind a firewall:
  - SIP signaling: UDP/TCP 5060
  - RTP media: UDP 10000–20000 (or per your provider specs)

## Additional Recommendations

- Reboot your modem/router weekly to clear cached errors.
- Avoid VPNs while using SNAP unless your system is configured for it.
- Contact your IT or provider if you consistently experience quality issues.

Quality of Service, a networking concept that prioritizes certain types of traffic to ensure performance and reliability, particularly for voice and video communications.

Session Initiation Protocol, a signaling protocol used for initiating, maintaining, and terminating real-time sessions that include voice, video, and messaging applications.

Session Initiation Protocol Application Layer Gateway, a feature in routers that can interfere with VoIP communications by modifying SIP packets.
