As part of this commitment, your support team may ask you to run our **Network Diagnostic Tool**. This is a quick, safe, and easy process that helps us analyze your internet connection to ensure your phone calls are crystal clear and reliable. ### Why are we doing this? Before we set up your new phones or troubleshoot a call quality issue, we need to check the **"health" of your network**. This tool helps us identify firewall blocks, router settings, or internet service provider configurations that might affect your calls. ### What you will need: 1. **A Computer**: A Windows or Mac laptop/desktop. 2. **Network Access**: This computer must be plugged into the **same internet network as your phones** (via Ethernet or Wi-Fi). Please **do not use** a mobile hotspot or a VPN, as this will give inaccurate results. 3. **The Email**: You should have received an email from your technical contact with specific instructions. ### **Step-by-Step Guide** We have broken this down into three simple steps. #### **Step 1: Download the App** 1. Open the email you received from your technical support team. 2. Click the **Download Link** provided in the email. 3. Download and install the **APP GUI** on your computer (just like you would install any other program). 4. **If you are asked for Admin permissions**, please allow it (this helps the tool check network settings). #### **Step 2: Get your "Test Link"** 1. Look back at the email you received. 2. Find the **Test Link** (it will look like a long web address/URL). 3. **Copy** this link (Right-click > Copy). ![](https://cdn.us.document360.io/3aabdf30-3e12-42ad-8192-dd2610fd289c/Images/Documentation/image-QPU4CRV0.png) #### **Step 3: Run the Test** 1. Open the **APP GUI** on your computer. 2. You will see a box asking for a "**Test Link URL**." 3. **Paste** the link you copied from the email into this box. 4. Click the **Run Diagnostic** button. 5. **Wait:** The app will run a series of checks. This usually takes less than a minute. Please don't close the window while it is running. ![](https://cdn.us.document360.io/3aabdf30-3e12-42ad-8192-dd2610fd289c/Images/Documentation/image-5205MFOV.png) ### **What happens next?** Once the test finishes, **you don't need to do anything else!** The results are automatically sent to your technical support team. They will review the data and contact you if they need anything else. ### **Frequently Asked Questions (FAQ)** --- ### #### Absolutely not. The app only checks network information (like IP addresses and port availability). It does not scan your personal files, read emails, or collect any sensitive business data. #### If the app shows an error, simply take a screenshot and send it to your technical contact. Our team is standing by to assist you. #### No, you do not need an account. The unique "Test Link" from your email is your access key. ****Can I run the test if I am working from home?**** Yes, but only if your work computer is connected to the same internet as your office desk phone. If you are on a different network (like a coffee shop Wi-Fi), the results won't be accurate for your office setup.
