Configure native VoIP on Android without any application

Android terminals natively support the use of VoIP with the possibility of configuring one or more numbers. We did the test, using a service that assigns a number for free with which you can call other users for free and at affordable rates, compared to many operators, fixed and mobile numbers. It is about messagenet.com.

 

What is VoIP and how does it work?

VoIP (Voice over IP) is the technology with which it is possible to make Internet calls, initially only from one VoIP number to another, or only via the Internet. Recently, the various services available online also allow VoIP calls to be made to traditional landline numbers and telephone operators.

Pro

  • A VoIP number can be configured on several devices, so it is possible to "bring" your number with you on a mobile phone and at the same time use it at home or on your PC.
  • You can save your conversations
  • Null, or minimal, costs around the world. 
  • More numbers on the same device
  • Possibility of more simultaneous callse

Cons

  • You need to have a connection Flat, not in time, otherwise free calls will repay you with your ADSL offer.
  • Need a good ADSL to avoid annoying lag (latency, delay) or even echo.

 

Native VoIP configuration on Android

As the title suggests, in this article we will explain how to configure a VoIP number on Android via the native options, without using any apps. Obviously you can also do it via the app, you can find dozens of them on the Play Store and even outside it.

The only requirements are Android higher than the 4.0 version (correct me if the Internet call is also present on previous versions) and a VoIP number that you can request from any Internet service, obviously calculating the most convenient one for you, or use a number that you already have , maybe active from the request of your home ADSL offer.

For the VoIP numbers of this guide, we have tried Messagenet as I have already mentioned, which offers a free number (freenumber) or a smartnumber on subscription with more services as well as fax, sms and other services found on the site.

 

Registration

Register on Messagenet (or skip this step if you have a VoIP number or if you choose another service) entering all your data and your phone number to be able to activate the number. If you choose not to use your phone number you will need to send a document. At the end of the registration you will receive an email to confirm and an SMS with the code to verify. Having done this receive a second email with the data to log in and a last email with the credentials to configure your device (Android in our case).

Set up Android

The configuration of the Android terminals is very simple, the tests have been done on KitKat (Android 4.4) and on MIUI (Android 4.1.2) and reaching the settings can be different from version to version, but just find Internet call settings. I will proceed using Android 4.4 KitKat as a reference.

start phone (the native app with which you dial the number), then press the 3 vertical dots at the bottom right and Settings, and you will find “Call settings”. Open and find "Internet Call Settings"

Through "Use Internet Calls" choose in which case to use these calls, instead press "Account" for the configuration.
Enter the username that was sent to you by email, password and server, EXCLUDING the port. The server will then be sip.messagenet.it and check that the port is set to 5060 or 5061 among the optional settings.

The result will be what you see in the second image. Ticking "Receive incoming calls" to allow other numbers to call you and if everything is set up in the right way, "Receive active call" will be displayed under your account.

At this point you can call for free the VoIP numbers from your Android, even if you want directly from the site, it's enough Java, or configure your PC following the instructions on the site itself!

 

Our test

Our test was made by two quite distant cities, both Italian, and with completely different ADSL providers. On the one hand Tiscali, on the other Linkem (WLAN). The first with low ping (around 30 ms), the second with ping on 130 ms.
Obviously, as already mentioned the call quality can depend on the Internet (speed, ping) with the result I had (with 130 of ping) a poor reception and a bad transmission.
A second test was made with the data connection (Wind) on my part. The reception had improved enough, the transmission deteriorated. After 2-3 seconds, I listened to everything I was saying, through an annoying echo to say the least. 
Data consumption: 1,3 MB consumed in 2 minutes 18 seconds of "conversation".

I hope that this bad quality is really due to the connections and not to the service.
