Can You Use VoIP Over Starlink?

Can You Use VoIP Over Starlink? Today we’ll find out more about using VoIP over Starlink in the following article and how Plexatalk can help your business get VoIP running over Starlink.

Voice over Internet Protocol (VoIP) has revolutionised the way we communicate by enabling voice calls over the internet. With the advent of Starlink, SpaceX’s satellite-based internet service, the question arises: can you effectively use VoIP over Starlink? Let’s explore this topic in depth.

What is Starlink?

Starlink is a satellite internet service developed by SpaceX, designed to provide high-speed internet access to remote and underserved areas around the globe. By using a constellation of low Earth orbit (LEO) satellites, Starlink offers reduced latency and improved speeds compared to traditional satellite internet providers.

Starlink is especially beneficial for individuals and businesses in rural or isolated areas where conventional broadband options like fibre or cable are unavailable. It is also a promising solution for mobile setups like RVs, boats, or disaster recovery operations.

Why Use Starlink Over 4G/5G?

While 4G and 5G networks are increasingly prevalent, they often come with limitations that Starlink can address:

  1. Coverage: Starlink provides internet access in areas where 4G and 5G signals are weak or non-existent.
  2. Bandwidth: In some locations, 4G/5G networks can become congested, leading to slower speeds. Starlink’s satellite network can offer more consistent performance.
  3. No Dependence on Mobile Networks: Unlike 4G/5G, which relies on proximity to cell towers, Starlink’s satellite coverage is independent of terrestrial infrastructure.
  4. Performance in Remote Locations: For individuals in extremely remote locations, Starlink often outperforms mobile networks in terms of speed and reliability.

However, 4G/5G networks might still be more suitable for users who require portability without the need for satellite equipment or for areas with strong cellular infrastructure.

Understanding Starlink’s Internet Speeds and Latency

Starlink promises internet speeds ranging from 50 Mbps to 250 Mbps, with some users reporting speeds exceeding 300 Mbps in optimal conditions. Latency, a critical factor for VoIP, typically ranges between 20 ms to 40 ms. However, in congested areas where network demand is high, speeds can drop to as low as 30 Mbps, and latency may increase.

Can You Use VoIP Over Starlink?

For VoIP, the general requirement is a stable internet connection with at least 100 Kbps per VoIP line. Starlink’s typical speeds far exceed this baseline, making it technically feasible for VoIP. However, fluctuations in speed and latency can impact call quality, especially during peak usage periods.

How Network Congestion Affects VoIP Usability

As more users connect to Starlink’s satellite network, bandwidth is shared among them, leading to potential congestion. During these periods, you might experience slower speeds and higher latency. These factors can cause issues like:

  • Dropped Calls: Insufficient bandwidth may lead to call disconnections.
  • Jitter: Variability in latency can cause voice distortion.
  • Delay: Increased latency can result in noticeable lag during conversations.

To mitigate these issues, it’s crucial to optimise your network for VoIP traffic.

Optimising VoIP Traffic with QoS

One effective way to ensure reliable VoIP performance is by using a router that supports Quality of Service (QoS). For instance, a DrayTek router allows you to prioritise VoIP traffic over other types of internet traffic. By configuring QoS settings, you can allocate sufficient bandwidth to VoIP calls, ensuring clear and uninterrupted communication even during peak internet usage.

Other routers that support QoS include:

  • TP-Link Routers: Many models come with built-in QoS capabilities.
  • Open-Source Solutions: Building your own router with OpenSense or pfSense provides advanced customisation options for prioritising VoIP traffic.
  • Netgear and ASUS Routers: Some models feature easy-to-configure QoS settings.

Here’s how QoS works:

  1. Traffic Prioritisation: Assign higher priority to VoIP packets compared to regular internet traffic.
  2. Bandwidth Allocation: Reserve a specific amount of bandwidth exclusively for VoIP.
  3. Congestion Management: Automatically adjust traffic flows to prevent overload.

With QoS configured on a reliable router, you can significantly enhance the quality of your VoIP calls over Starlink.

How Plexatalk Optimises VoIP on Starlink

At Plexatalk, we understand the challenges of using VoIP over variable internet connections like Starlink. That’s why our system is designed to be resilient and adaptive:

  • Advanced Codec Support: PlexaTalk uses efficient codecs like Opus and G.729, which consume minimal bandwidth while maintaining excellent call quality.
  • Adaptive Jitter Buffers: Our system adjusts dynamically to account for variations in latency, minimising jitter and distortion.
  • Traffic Shaping: PlexaTalk integrates seamlessly with QoS settings, ensuring VoIP traffic always gets top priority.
  • Cloud-Based Redundancy: Even if local internet conditions falter, our cloud-based infrastructure ensures calls remain stable.

Practical Tips for Using VoIP Over Starlink

  1. Invest in a High-Quality Router: A DrayTek, TP-Link, Netgear, ASUS, or an OpenSense/pfSense-based custom router with advanced QoS capabilities is essential.
  2. Monitor Network Usage: Avoid heavy downloads or streaming during important VoIP calls.
  3. Test and Tweak: Regularly monitor call quality and adjust QoS settings as needed.
  4. Upgrade Equipment: Ensure your Starlink dish and modem are updated for optimal performance.

Frequently Asked Questions (FAQs)

Which UK VoIP provider works with Starlink?

Plexatalk is a reliable UK VoIP provider that works seamlessly with Starlink. Our system is designed to adapt to varying internet conditions, ensuring stable and high-quality calls.

How to set up QoS for VoIP?

To set up QoS for VoIP, log into your router’s configuration page. Look for the QoS settings, enable QoS, and prioritise VoIP traffic by adding your VoIP device’s IP address or assigning higher priority to the ports used by VoIP services.

Does VoIP work over Starlink?

Yes, VoIP works over Starlink. With its fast speeds and relatively low latency, Starlink can support VoIP calls effectively. However, proper configuration, including QoS, is essential for optimal performance.

Final Thoughts

Using VoIP over Starlink is not only possible but can be highly effective with proper setup and optimisation. While Starlink’s speeds and latency generally support VoIP, fluctuations during peak times highlight the importance of QoS and reliable VoIP systems like PlexaTalk. By prioritising VoIP traffic and leveraging robust tools, you can enjoy crystal-clear calls over Starlink’s satellite internet.
