What is the VoIP Call? 

VoIP or Voice over internet protocol is a relatively new telephony system.  The system is based on Internet technologies.  A VOIP call is voice communication over an IP network. For a VoIP call, the caller has either a softphone or IP phone for dialing a number.  For a soft-phone, a user has to install a software client on the mobile phone or PC and set up the VoIP account on the phone for receiving and initiating calls over the IP network. A soft-phone is a dedicated device that connects over internet lines for voice calls and has all software necessary for calls.

Benefits of VoIP call:

We all are using a VoIP in some forms. Either it is a skype call or from any other application.  But a VoIP phone works as a normal phone. It has a number which can be reached from any corner of the globe.  There are many advantages, few are listed below.

Low-cost call:

Mainly when we talk about long-distance calling, the first thing comes to mind the cost for international calls. A VoIP user mainly pays for the internet. This brings the call cost dramatically low.

Reduces Roaming Cost:

When a phone comes into roaming, then call rates changes. For international roaming, the cost increases a lot.  This is because roaming agreements between the mobile operators and network providers changes from county to country. With VoIP, a mobile device can use the free internet connection over WiFi.  As we know that in most places, Airports, Hotels, etc, free wifi is available.  A VoIP user can easily connect to the internet for voice communication.

Increased Coverage :

Cell phone towers are everywhere.  A phone with VoIP capability can use the cellular tower when in range of a telecom network and WiFi network (if available) when there is no telecom cell coverage.  This enables a much broader coverage to a mobile subscriber a VoIP call.

VoIP Disadvantages:

VoIP might not be allowed at all the places. This is because of security reasons.  VoIP does not use the telecom network as like normal call.  So the local mobile operators can not keep track of calls. Which may be a major security threat.

VoIP is not beneficial for a mobile subscriber, who is allowed to use very little mobile data or the internet.
