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 softphone, 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 softphone 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 VoIP in some form. 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.
Mainly when we talk about long-distance calling, the first thing that comes to mind the cost of 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 change 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 might not be allowed at all places. This is because of security reasons. VoIP does not use the telecom network as a normal call does. 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.
