# 🛠️  Troubleshooting Call Quality Issues

---

##

If you are experiencing issues such as:

- Dropped calls
- One-way audio
- Choppy or robotic sound
- Delays in conversation

We first need to rule out **network stability problems** before proceeding with deeper investigation.

---

### 🔍 **Step 1: Perform a Network Stability Test**

⚠️ **Important:**
The network test **must be run on the same network as the phone or VoIP device experiencing issues**.

✔️ **Preferred Setup:**

- Connected to the **same switch, router, or Wi-Fi extender** as the phone system.

✖️ **Avoid:**

- Mobile data
- VPN connections
- A different Wi-Fi or network

#### **Test Instructions:**

1. Open this link:
   👉 [https://speed.cloudflare.com](https://speed.cloudflare.com/)
2. Click **"Start"** to begin the speed and stability test.
3. Wait for the test to fully complete.
4. Take a **screenshot of the final results**.
5. Send the screenshot to our support team for review.

### 🔄 **Step 2: Next Actions Based on Test Results**

| **Result** | **What Happens Next** |
| --- | --- |
| ✅ **Network Stable** | Our engineering team will continue to investigate potential system-related causes. |
| ⚠️ **Network Unstable** | Please contact your **local IT department** to address the network issue (e.g., packet loss, jitter, latency). |

### ℹ️ **Why This Step is Critical:**

Network instability is a common cause of VoIP call quality problems. Testing from the correct network environment ensures an accurate diagnosis and prevents unnecessary troubleshooting delays.
