VoIP Disadvantages


1. Requires an Adequate Equipment

If your building uses outdated firewalls, routers, or cable modems to create an internet connection, you might face poor quality VoIP service. If the glitch occurs while on a call, update the router software or replace older equipment and reconfigure network gear.

But, to have a smooth running VoIP service, you must have all the adequate equipment and dispose off all older components that require an upgrade or replacement.

2. Security Issues

Anything that involves the use of the Internet often raises security concerns as you might experience viruses, denial of service attacks, malware, identity theft, and other issues on using this technology. Even if you have taken measures to remove vulnerabilities, in most cases, call tampering and phishing attacks occur.

Hence, it is best to immediately report any suspicious activity, such as unusual call traffic that occurs to the VoIP service provider.

3. Poor call quality

Packet loss or poor connection is often the main reason behind poor voice quality. As a result, you might hear echoes, noise, or different voices in the background.

You can use the VoIP SIP test or other tools to review connections and check for packet loss. Also, the option to register the softphone with the server is not possible in some cases. In order to make phone calls using a softphone on your laptop, we recommend using firewall testing tools for checking UDP ports.

4. Bandwidth dependency

Internet connection is a shared community resource used by multiple people at the same time. As a result, there are high chances that the speed and quality of service might reduce, especially during peak hours. It might also cause overload on your system resulting in a lack of bandwidth for VoIP services.

Experts cannot control internet issues every time. Do you know a typical VoIP connection (G711 codec) demands 80k for each call? However, the range varies for other codecs based on their requirement. So, make sure to run Internet speed tests beforehand and check with the selected provider.

By running a simple Internet test, you can get more information about the bandwidth and avoid this disadvantage.

Overloading can also lead to poor call quality. Hence, try to avoid doing extra tasks involving the use of the Internet when making a VoIP conversation.

5. Security and extra costs

Internet technology security is a major consideration with VoIP. Possible threats include identity and service theft, viruses and malware, spamming, call tempering and denial of service attacks.

Also, to use VoIP services, it is a must to plugin your equipment into a power resource. If there are interruptions in the power system, you might not be able to communicate properly using this technology. In some cases, people also use an uninterruptible power supply, but it is not a full time solution.

Lastly extra costs can be incurred if you use VoIP to phone someone without VoIP capabilities.
