How to make VoIP SIP calls on Android

VoIP phone service background

VoIP phone services have been steadily increasing in popularity. Today, the most widely used VoIP protocol is the Session Initiation Protocol or SIP. But there is also recent technology used to handle VoIP calls over web-based applications called WebRTC.

WebRTC is not a separate technology to SIP. It is just a set of tools (SDK) that work together with SIP Trunk infrastructure to offer more versatile apps under the user side app. So VoIP providers keep in place the SIP servers and networks but under client-side now customer can choose to use: “Pure SIP phone client” or “WeRTC based communications”

VoIPstudio Android and iOS mobile phones apps are already using WebRTC but as you will discover later in this article you can still make and receive telephone calls on VoIPstudio using chrome native SIP client or any Third-party SIP app. Also, in later articles, we are going to discuss the differences between each technology and talk about mobile apps reliability.

In the current article about VoIP calls on Android, we are going to explain how Android users can take advantage of VoIP telephone calls and the array of possibilities Android users have with VoIP. In this guide, you will learn how to configure your Android phone to make SIP calls.

Virtually all hosted VoIP services and local deployments are based on SIP and integrate with the Public Switched Telephone Network (PSTN).

The increasing use of smartphones in the enterprise and beyond is creating new needs. Many users are looking for a solution that allows them to make SIP calls on Android phones.

This is all possible and is very easy to do. Let’s find out how.

What is SIP Protocol?

In the world of telecommunications and network engineering, a protocol is a set of rules that can be used by two entities to transmit data, information or signals. These rules define the syntax, method, standards and semantics of communication, to minimize confusion and make sure communication sessions can proceed efficiently.

The Session Initiation Protocol – which is abbreviated to SIP – is one such protocol that is used for signalling, setting up and controlling multimedia sessions. These sessions may involve audio, video, instant messaging, 2 callers, multiple callers or any combination of the above variables.

What the end-user considers a single phone call is actually divided into two phases – ‘call set up’ and ‘media transfer.’ SIP is used in the call set up phase and implemented in the application layer. SIP is used to initiate the call between two or multiple parties via SIP proxy servers. Once the initial parameters have been established, the actual call and media data transfer happens directly between the endpoints in a peer to peer fashion.

Requirements for VoIP phone calls on Android

Basically, VoIP phone calls can be made and received from any device that supports the SIP protocol, which includes Android devices. Google in its FAQ list also tells you how to configure SIP calling on Android (they call it Wi-Fi calling).

SIP support has been present in Android for a long time, ever since it was introduced in version 2.3 a.k.a. Gingerbread on 2010.

What it means is that any modern smartphone (as long as it was purchased in the last three or four years!) that runs the Android operating system will be able to make SIP calls and will let for integration with VoIPstudio.

Some hosted VoIP phone vendors offer dedicated smartphone apps on iOS and Android that allow their users to make voice calls via their service. However, not all of them do so, but that doesn’t mean you cannot make SIP calls through those services.

For instance, VoIPstudio is a great service that supports the SIP protocol, so a customer can use their account credentials on any Android SIP client to make calls.

There are many third-party VoIP phone apps that support SIP calling, whether or not they offer VoIP services. Some of them are free while others require a one-time payment.

While the latter apps may provide extra features, not every user will require them. It is certainly possible to make SIP calls from Android devices without having to pay anything extra.

How to Set Up SIP On Android

Configuring SIP in Android is not a difficult task. It is a straightforward process that should not take more than a few minutes on any phone.

All you really require is an account with a VoIP phone service provider and an Android phone.

As long as you have all the details such as username, password and server/domain address, you can start making and receiving calls once you finish the Android SIP client configuration.

Please note not all Android devices have the same release and features. We have to say lately we are seeing some Android OS manufacturers blocking this embed SIP feature on their devices. If this is happening under your smartphone you will need to use our VoIPstudio Mobile App or any third-party SIP app.

Many users forget to check the setting when setting up their account and thus end up missing a lot of calls.
