Why Network Tests Matter
VoIP systems rely on your internet connection to make and receive calls. Unlike traditional phone lines, where a dedicated infrastructure ensures voice quality, VoIP shares bandwidth with all other data types transmitted through the network. This means that if your network is not optimized, you may experience problems such as dropped calls, poor sound quality, delays, and jitter.
Businesses that use virtual business phone systems must ensure that their networks are up to the task of handling multiple simultaneous voice calls. A solid and reliable connection is crucial for remote teams, as they may rely entirely on making calls from computers.
Therefore, running VoIP speed tests and network checks is a proactive step in ensuring smooth operation and avoiding disruptions that could harm customer relationships and internal communications.

Download Speed
Measures how fast your connection can receive data. Ideal: >10Mbps
*Insufficient download speed can cause choppy audio and video freezing during calls.*
Upload Speed
Measures how fast your connection can send data. Ideal: >5Mbps
*Low upload speeds can cause your voice and video to appear delayed or distorted to others.*
Latency
Measures response time for data travel. Ideal: <100ms
*High latency (>150ms) can cause noticeable delays during VoIP calls and create echo effects.*
Jitter
Measures variation in packet arrival times. Ideal: <30ms
*Jitter above 30ms can cause voice distortion, leading to robotic sounds or broken sentences.*
Packet Loss
Measures lost data packets during transmission. Ideal: <1%
*Even 1% packet loss can cause noticeable audio gaps and dropped words in conversation.*
Round Trip Time (RTT)
Total time for data to travel back and forth. Ideal: <200ms
*High RTT (>300ms) creates noticeable conversation delays, similar to satellite phone calls.*
Understanding VoIP Call Quality Issues: Common Challenges and Solutions
For small businesses, the quality of phone calls is essential to building relationships, handling customer inquiries, and maintaining professional communications. VoIP systems can offer great flexibility and cost savings, but like any technology, they come with their own set of potential challenges.
Choppy Audio and Delayed Responses
Cause:
Typically, this happens when there's too much network congestion, meaning too many devices or applications are competing for bandwidth.
Solution:
Prioritize VoIP traffic by enabling Quality of Service (QoS) settings on your router. QoS will help ensure that VoIP calls get the bandwidth they need, even during busy network times. Alternatively, limit the number of high-bandwidth activities like video streaming or large file downloads while making calls.
Echoes During Calls
Cause:
Echoes are often due to equipment issues, such as microphones or speakers that are too sensitive or too close together.
Solution:
Encourage users to use headsets with noise-canceling features, which can significantly reduce echo. Also, check your VoIP equipment's settings to see if there's an echo cancellation option.
Call Drops and Connection Loss
Cause:
Weak or unstable internet connections are the main culprit here. If the connection fluctuates, it can cause calls to drop suddenly.
Solution:
Check with your Internet Service Provider (ISP) for consistency issues and consider upgrading to a more stable plan if drops happen frequently. Additionally, wired connections are more stable than Wi-Fi, so consider connecting your VoIP devices directly to the router.
Poor Quality During Peak Hours
Cause:
Network congestion increases during high-usage times, particularly when many employees or applications are online simultaneously.
Solution:
If peak-hour issues persist, consider upgrading your internet speed or discussing business-level packages with your ISP that prioritize VoIP quality. Also, identify and manage non-essential activities during peak times to free up more bandwidth for calls.
Key Takeaway
By understanding these common VoIP issues and simple, budget-friendly solutions, small business owners can take control of their VoIP quality. Consistently monitoring and optimizing network settings will allow VoIP systems to perform smoothly, helping your business maintain the professionalism and reliability that your customers expect.
Optimizing Your Network for VOIP
- Upgrade Your Internet Plan if bandwidth is insufficient
- Implement QoS settings to prioritize VoIP traffic
- Use wired connections instead of Wi-Fi when possible
- Reduce network congestion during important calls
- Use a VoIP-optimized router with advanced QoS features
Step-by-Step Guide to Setting Up QoS for VoIP on Your Network
Quality of Service (QoS) is a network feature that helps prioritize certain types of data traffic, ensuring VoIP calls get the bandwidth they need for smooth and clear communication. For small business owners, setting up QoS can make a significant difference, especially if there are multiple devices or users on the network.
What is QoS and Why Is It Important for VoIP?
QoS prioritizes your network traffic so that voice data (VoIP calls) takes precedence over other types of traffic, like streaming or downloads. This is essential for preventing issues like dropped calls, lag, or choppy audio, especially during times of high network usage.
1Access Your Router Settings
Log into Your Router
Open a web browser, enter your router's IP address (usually something like 192.168.1.1
or 192.168.0.1
), and log in with your username and password.
Locate the QoS Settings
Every router interface is a bit different, but QoS settings are usually found under sections like "Advanced," "Traffic Management," or "Applications and Gaming."
2Enable QoS
Choose QoS Type:
Device Priority
Prioritize specific devices, like your VoIP phones or computers, ensuring they get the required bandwidth.
Application Priority
Prioritize VoIP applications like Zoom, Teams, or specific VoIP services.
Bandwidth Priority
Set bandwidth limits for different types of traffic, reserving the necessary bandwidth for VoIP.
3Set Priorities
Add Your VoIP Device or Application
Locate your VoIP phone, computer, or VoIP software in the list of devices or applications. Select it and set it to High Priority or Highest Priority.
Specify Bandwidth Allocation
Some routers let you specify the exact amount of bandwidth allocated to VoIP. For small businesses, dedicating a portion of your bandwidth (e.g., 30-40% for VoIP) can help maintain call quality.
Limit Non-Essential Devices
If other devices are regularly using high bandwidth (e.g., security cameras, streaming devices), you can set them to lower priority to free up bandwidth for VoIP.
4Save and Test Your QoS Settings
Save Changes
Make sure to save your settings before exiting the router interface.
Test Call Quality
Once QoS is enabled, make a few test VoIP calls during peak hours to see if there's an improvement in call quality. Notice if there are fewer dropped calls, less lag, or clearer audio.
Troubleshooting Tips
- If your router doesn't have QoS settings, consider upgrading to a VoIP-compatible router or a business-grade router that supports QoS.
- QoS works best when devices are on wired connections, as Wi-Fi can still introduce variability in call quality.
- If your business grows and more devices are added, revisit QoS settings to ensure VoIP traffic remains prioritized.
Key Takeaway
Setting up QoS is a straightforward and highly effective way to ensure your VoIP calls maintain high quality, even during busy times. By following these steps, small business owners can enhance their VoIP performance and provide consistent, professional communication.
