Review Of The Best Free VoIP Applications Worth Trying Out !!
Now it’s time to dig deep into the details of each of those mentioned above in the list. You will get a brief overview for a quick ready reference to guide in your selection process. Let’s explore each of them now :

The launch of the Google Hangouts Meet is now being developed as the business graded collaboration platform. Here you can exchange files and documents easily with others.
Hangouts include the opportunity to make free voice calls to other Hangouts users and charge users to dial landline and cell phones internationally (via pre-registered credit) with the exception of free calls to the United States and Canada. This has Android and iOS versions separate.
CSIPSimple is an open-source application that allows Android smartphones to have SIP-telephony. You need Android version 1.6 or higher to run this VoIP calling program.

The WiCall call framework is based on CSIPSimple and is available in many languages (including German, English and Chinese) for iOS (from version 4.3), Android (from version 2), and Windows Phone (version 8 or 8.1). The size of this application is of 7 MB (Windows Phone) to 9.1 MB (Android) in the middle range.
WiCall offers IP telephony over a WLAN network or 3G/4G. This can trigger data transmission costs to be incurred for the latter. Overseas calls cost $0.01 to $0.03 per minute. You need to replenish your prepayment credit for this. WiCall is one of the most competitive service providers.
Sipdroid is one of the most common, and the smallest Android calling application with a size of 1 MB. The program integrates into the operating system of the smartphone and allows for VoIP calls via WLAN or 3G/4G.
You need a provider with Sipdroid which provides the telephony function ( e.g. a virtual phone system). You can also connect and make calls using Skype account.
The Viber App isn’t a traditional calling tool. Although it allows us to make calls over the Internet and provides messaging apps, all participants must be registered with Viber.
To do so, the contacts are synchronized by the application and they inform you which ones are registered with Viber. Viber can be used on tablet PCs and is compatible with Android 2.3, iOS 7, and Windows Phone 8 or higher.

Skype is undoubtedly the best-known Internet telephony service. You would need to open a Skype account, so you will make free calls to your internet friends, or to landlines so cell phones, with credit running out.
Skype to Skype calling is completely free. However, to non-Skype calls, you need to buy credits. Skype is famous for the video chat feature. But you can pretty simply make free VoIP calls to any Skype user. Even to a landline or Skype users. A phone number will be assigned when you purchase credits.
This is indeed compatible with all the major OS (Windows/Android/iOS etc) based devices.
Recently the Facebook-owned “WhatsApp” has begun offering an IP telephony service. But, as like Viber, you can only make free calls only to your other WhatsApp friends. Because of the dubious aspects of data security which have often been criticized by WhatsApp, a comparison with other VoIP providers is advisable.
Free VoIP Service with Phone Numbers !!
As stated earlier, we can easily make free in-app VoIP calls, also to other non-app calls we need to buy credits. So owning a free VoIP service with phone numbers is really a great feeling. So let’s see the top three free VoIP service with phone numbers now :

3. Google Hangout
You can enjoy many good features with this, with Google voice app, you can quickly set a call forwarding. If you have a Google dialer app installed to make in the US calls for free. Also if you install the Google Voice account, you can make free VoIP calls with an assigned number.
Android, iOS, and Windows Smartphones have a number of SIP clients. Compare for yourself which apps are ideally suited to you and which call app basically meet your exact needs.
You should bear in mind, however, that if you are on the move in the different mobile networks, you will have to pay for the data usage-unless you have booked a flat rate alternative.
Also overseas, where the amount of data available is usually no longer active, you should always bear this in mind and dial into a WLAN available before making calls with the calling app. Consult with your virtual PBX provider even to see if they don’t provide an acceptable calling app.
