Cons of VoIP

Wall Power Dependency

No power means No VoIP.

Current phones are supported by the power provided through central connections.

This means even if there is a power failure, the phone still works.

But the same is not the case for VoIP.

Absence of Emergency Calls

VoIP uses IP addressed phone numbers.

Emergency call service like 911 won’t work through this platform because of this.


If the speed of the internet is low, users might not be able to have a good experience with VoIP features.


Since it is dependent on the internet, it is prone to security threats like viruses and hacking.

System Dependent

Its efficiency is also dependent on the ability of the user system.

If a user experiences VoIP platform services on his softphone and by chance, he has to open a new window simultaneously.

The quality of VoIP services is now wholly dependent on how this softphone reacts to multiple tasks.

If the softphone is not efficient enough to handle multiple tasks, then VoIP services can be affected.

VoIP has surely started dominating the communication sector. With the current Covid-19 situation, it has proved to be a reliable platform for communications.

Businesses who have adopted VoIP as their primary source for communications have saved a lot on their phone bills and improved daily business operations because of its flexibility.
