A Guide to Troubleshooting Common Telecom Issues

Last updated: 22 Jun 2023

Telecom issues are problems or disruptions within a business’s telecommunication systems, such as phone lines, internet connections, and other communication services. These issues can significantly impact a business’s daily operations, leading to lost productivity, missed opportunities, and even damaged customer relationships. This comprehensive guide will discuss the importance of identifying and resolving telecom problems, explore the most common issues businesses face and their underlying causes, and provide step-by-step strategies to resolve each issue. 

The Importance of Identifying and Resolving Telecom Problems

Quickly and efficiently identifying and resolving telecom issues is essential for business owners, as these problems can directly affect their ability to communicate with customers, suppliers, and team members. Unresolved telecom issues can lead to increased costs, decreased efficiency, and negatively impact the business’s overall reputation. As such, businesses need to plan for troubleshooting and resolving telecom issues as they arise.

Common Telecom Issues Faced by Businesses and Their Underlying Causes

1. Poor Call Quality

Poor call quality can manifest as garbled or distorted speech, echoes, or excessive background noise during phone calls. Various factors can cause this issue:

  • Network congestion: High traffic levels can cause delays in data transmission, resulting in poor call quality. 
  • Outdated hardware: Older phone system hardware may not handle modern communication demands, reducing call quality. 
  • Interference from other devices: Electronic devices or large metal objects near your phone system can cause interference, negatively impacting call quality. 

2. Dropped Calls

Dropped calls happen when a phone call is disconnected unexpectedly, and this can happen because of the following: 

  • Weak signal strength: Insufficient signal strength can cause calls to drop, particularly in areas with poor coverage or physical obstructions like walls and buildings. 
  • Network congestion: High levels of network traffic can cause calls to be dropped as the network struggles to maintain connections. 
  • Faulty equipment: Malfunctioning hardware, such as phones or routers, can cause calls to be dropped. 

3. Slow Internet Speeds

Slow internet speeds can lead to sluggish website loading times, buffering during video streaming, and delays in sending and receiving emails. This issue can be caused by: 

  • Network congestion: Excessive network traffic can cause internet speeds to slow down, particularly during peak usage times. 
  • Low bandwidth: An internet plan with insufficient bandwidth may be unable to handle modern online applications’ demands, leading to slow speeds. 
  • Issues with the service provider: Problems with your internet service provider (ISP), such as outdated infrastructure or technical difficulties, can result in slow internet speeds.

4. Connectivity Issues

Connectivity issues can prevent devices from connecting to the internet or other network resources. These problems can arise due to the following:

  • Faulty cabling: Damaged or improperly installed cabling can cause connectivity issues.
  • Hardware issues: Devices may be unable to connect to the network due to hardware malfunctions, such as faulty routers, switches, or network cards
  • Network configuration errors: Incorrect network settings or configurations can cause connectivity problems.

5. VoIP Issues

VoIP issues can include poor call quality, dropped calls, or difficulty connecting calls. The following can cause these issues: 

  • Poor internet connectivity: VoIP relies on a stable internet connection, so any issues with your internet connection can directly impact VoIP performance.
  • Improper configuration: Incorrectly configured VoIP settings can cause issues such as difficulty connecting calls or poor call quality. 
  • Outdated hardware: Older VoIP hardware may struggle to handle modern communication demands, leading to performance issues.

Step-by-Step Strategies to Resolve Telecom Issues

Resolving Poor Call Quality

  1. Check for network congestion by monitoring your internet connection during peak usage times. Consider upgrading your internet plan for increased bandwidth if you notice a significant slowdown. 
  2. Inspect your phone system hardware and replace any outdated or malfunctioning equipment. All devices should be updated with the latest firmware and software. 
  3. Identify and eliminate any sources of interference, such as nearby electronic devices, large metal objects, or other wireless networks. Ensure that your phone system is positioned away from potential sources of interference.

Resolving Dropped Calls

  1. Assess the signal strength in your area by checking coverage maps provided by your telecom provider. If necessary, consider installing a signal booster or switching to a provider with better coverage in your location. 
  2. Monitor network congestion and consider upgrading your internet plan for increased bandwidth if necessary. Additionally, prioritize voice traffic on your network using Quality of Service (QoS) settings to reduce the likelihood of dropped calls.
  3. Inspect your phone system hardware and replace any outdated or malfunctioning equipment. Regularly update your devices with the latest firmware and software to ensure optimal performance. 

Resolving Slow Internet Speeds

  1. Evaluate your internet speed with an online speed test tool and compare the results to your service provider’s advertised speed. If a notable difference exists, contact your provider to address the issue. 
  2. Upgrade your internet plan for increased bandwidth, mainly if you frequently use high-bandwidth applications like video conferencing or large file transfers. 
  3. Optimize your network by ensuring all devices are updated and configured correctly. To improve performance, consider implementing network optimization tools, such as caching servers or content delivery networks (CDNs). 

Resolving Connectivity Issues

  1. Inspect all cabling and connections for damage, wear, or improper installation. Replace any damaged cables and ensure that all connections are secure. 
  2. Check your network hardware for malfunction, including routers, switches, and network cards. Replace or repair any faulty equipment as needed. 
  3. Ensure your network configuration settings are correct and current. If needed, seek guidance from an IT professional or your service provider to assist with proper network configuration.

Resolving VoIP Issues

  1. Troubleshoot your internet connection to resolve any connectivity issues affecting your VoIP performance. Consider upgrading your internet plan or implementing QoS settings to prioritize VoIP traffic on your network. 
  2. Verify your VoIP configuration settings and make adjustments as needed. Consult your VoIP provider’s documentation or support resources for guidance on the proper configuration. 
  3. Upgrade your VoIP hardware and software to the latest versions to ensure optimal performance and compatibility with modern communication standards.
