VoIP and Packet loss issues

VoIP is highly sensitive to packet loss, which can significantly impact call quality and even disrupt the ability to make or receive calls. Packet loss is the largest reason we have for support calls for our VoIP service.

What Is Packet Loss?

Every internet activity relies on the smooth transfer of "packets" — small units of data. Packet loss disrupts this flow, leading to noticeable issues in real-time communication such as video calls and VoIP phone systems. While browsers can resend missing packets, live interactions can suffer delays or distortions that can‘t be corrected on the fly.

Common causes of packet loss include:

Security breaches
Hardware failures
Network congestion

Signs of Packet Loss

Businesses might unknowingly experience packet loss, but telltale signs include:

Dropped calls during VoIP communication
Distorted audio or video in live meetings
Timeouts or inconsistencies in command prompts

To detect packet loss:

Open a command prompt on your PC.
Type: Ping 8.8.8.8 -t
Monitor the responses:
- A reply like Reply from 8.8.8.8: bytes=32 time=8ms TTL=118 indicates normal activity.
- Timeouts (Request timed out) or high time values (e.g., time=128ms) suggest packet loss.

Troubleshooting Packet Loss

“It’s crucial for business owners to understand their networks and address issues promptly. Often, packet loss isn’t the provider’s fault but stems from internal network challenges.”

— Juliet Moran, TelephoneSystems.Cloud

Follow these steps to diagnose and resolve packet loss:

Update Hardware and Software: Ensure routers, switches, and other network equipment are updated with the latest firmware.
Identify Recent Changes: Network modifications, like duplicate IP addresses, can trigger packet loss. Pinpointing recent changes can help locate the problem.
Monitor Bandwidth Usage: Viruses or insufficient bandwidth can lead to packet loss. Scan devices regularly and consider alternative connections, such as 4G or satellite, in low-bandwidth areas.
Optimize Wi-Fi Networks: Overloaded Wi-Fi networks can experience interference. Prioritize wired connections where possible, and minimize the number of devices connected to Wi-Fi.
Check Wired Connections: While wired networks are more stable, damaged cables can cause packet issues. Test and replace deteriorated wires.
Use Network Monitoring Tools: Employ online tools to track performance, detect anomalies, and pinpoint bottlenecks causing packet loss.
Contact Your Internet Provider: If issues persist outside your internal network, contact your provider for troubleshooting. They can check external wiring and resolve cabinet-level problems.

"Honestly, this company was incredibly easy to deal with and extremely helpful. The online ordering process was straightforward, and the staff were always on hand to help. We moved all 13 telephone numbers away from BT after BT Local Business completely messed up our accounts, and the transition couldn’t have been smoother. Number porting, invoicing, and online payments were simple and hassle-free. The equipment was true plug-and-play — a total breeze. Best of all, we now have one clear, straightforward bill, and there’s always someone available when we need support. Absolutely brilliant service — love you guys."

By Queensborough Group BB

"About on year ago I took a decision that I have been trying to take for about ten years. The decision? To move my small family business to VOIP phones and hope that they now work OK (2022!) , with good support and fallback systems. Well I did not need to worry .... I chose a local company with a good reputation and off we sailed. The experience with Telephone Systems has been truly faultless and we have been handled with kid gloves all the way through. The system is excellent on call quality and we have flexible access to the same fixed monthly call charges via user mobile phones too. If you are looking at hosted VOIP service do give this company a chance to quote. Excellent service supporting our self install, no "hard sell", simple, fair and transparent capped pricing and no long term contract. We don't need anything else!"
By Endon Services Group
