Buyers guide


Last Updated: June 19, 2019

Choosing the right SIP client for business VoIP can be a daunting task. To begin with, what do all these abbreviations even mean? And which is the right Android, iPhone or desktop SIP client for you?

Even if you know what VoIP and SIP stand for—Voice Over Internet Protocol and Session Initiation Protocol, respectively—that doesn’t clarify what these technologies can do for you.

Luckily, SIP and VoIP clients are much simpler than they may seem. We’re here to help you understand the differences and pick the best app for your Android device or iPhone. This buyer’s guide will cover the basics that will help you get started in the market.

Here’s what we’ll cover:

Benefits of SIP Clients

What Are SIP Clients?

SIP clients are software applications built to run on mobile devices with internet connections. These apps facilitate over-the-top (OTT) communications, that is, communication channels that cut service providers out of the picture. Mobile VoIP apps allow you to send voice calls and SMS messages over a Wi-Fi connection.

SIP clients are examples of what is known as unified communications (UC) clients. Unlike simple VoIP softphones, which strictly allow you to make and receive calls over the internet, UC clients include expanded capabilities, such as voicemail, SMS and instant messaging, video conferencing and call settings.

Common Features of SIP Clients

SIP clients often include the following core capabilities:

Voice calling Make and receive calls through your internet connection.
Video calling and conferencing Place and receive video calls on devices with cameras. Some apps allow for video conferencing with multiple users.
Call history Track incoming and outgoing calls.
Voicemail Let callers leave voice messages when you’re not available, listen to voice messages, return calls and check voicemail left on one device from another.
Call settings Use remote control over call settings, route calls from office phones to mobile phones and login to accounts remotely.
SMS text messages Send and receive short message service (SMS) texts over internet connections.

The Vendor Landscape

To help you determine which SIP client is right for you, let’s take a look at a few popular products.
