Unified communications may be the default for communications experiences today, but few technologies have made UCaaS more accessible than softphones.

What are they precisely?

What is a Softphone?

A softphone is a form of software that creates a virtual phone as an app, enabling any device with an internet connection to make and receive calls.

  • This means any smartphone, tablet, desktop computer, and laptop can be used as a softphone.
  • Softphones are software-based phones that play an integral part in any UCaaS platform, providing the backbone for voice, video conference calls, meetings, messaging, and innovation.

How softphones differ from hardphones

Hardphones are physical desk phones; softphones are apps. Hardphones are more reliable but limited in features. Softphones offer mobility and advanced PBX access. Softphones scale easily; hardphones are fixed but user-friendly.

If you have a minute, dive into this quick video that covers the essentials of softphones:

Be it cost savings, scalability, or unifying communications, softphones are flexible enough to either replace legacy communications or integrate into larger operations.

What is VoIP? All to Know, in Simple Terms [2024 Update]

What Does a Softphone Do?

A softphone is an app that enables making and receiving calls over the internet without traditional phone hardware. They use a device’s internet connection for both voice calls, video calls, and MMS through a VoIP service.

Softphones have the functionality of a physical phone without a dedicated infrastructure to provide services. An Internet connection allows the app to access the VoIP provider’s network to make and receive incoming calls, without compromising on more modernized features like video calls, instant messaging, and MMS.

How Do Softphones Work?

Softphones connect to a VoIP service via the Internet, allowing calls, video call chats, and messaging on digital devices without traditional phone hardware.

Above all else, softphones are designed to be user-friendly. Developers of these apps know that they’re going to be used throughout different organizations, operating systems, and by users with all levels of technical expertise.

This means special care is paid to crafting software that anyone can pick up and use on a computer or mobile device.

Every software and hardware tool has specific features. Let’s examine the most important features of softphones.

The best softphone apps do much more than place calls. Look for top features like:

  • CRM integrations: Connect your calls with customer data instantly. No more juggling apps or losing info — everything is right where you need it.
  • Security and encryption: Secure softphone apps offer robust encryption protocols such as TLS (Transport Layer Security) or SRTP (Secure Real-time Transport Protocol).
  • Voicemail: Capture messages from missed calls with voicemail. Leverage an intuitive interface where users can playback, read, or even forward messages to an inbox.
  • Call quality: Crystal-clear audio is crucial when communicating in different languages. Keep your conversations professional and concise.
  • Caller ID: Identify incoming calls instantly. Prepare for conversations and manage your communications more effectively with advance knowledge of who’s calling.
  • Desktop and mobile apps: Access your professional phone system from any device. Maintain consistent communication capabilities whether you’re in the office or working remotely.
  • Video conferencing: Conduct face-to-face meetings remotely with ease. Facilitate team collaborations and client presentations without the need for travel.

Benefits

Why This Matters

Save Ongoing Costs by Using a Softphone AppCompanies can reduce their phone costs by up to 50% after switching to VoIP softphones. Startups benefit by reducing phone costs by 90% by avoiding in-house infrastructure as softphones are typically billed per user.
Maintain Work-Life Balance on the Same DeviceSoftphones create a way for employees to make and receive calls on their mobile devices, without using their personal phone numbers. This allows employees to balance between their normal phone and company-specific phone.
Softphones Don’t Need a Dedicated ConnectionHardware phones work on dedicated connections to ensure voice quality, such as a phone line. Softphones do not require any additional infrastructure and are designed to operate efficiently over an internet connection. VoIP softphone calls also consume less bandwidth than traditional telephone lines.
Eliminate Additional HardwareNo more desk phones and multiple lines, no more in-house infrastructure for telephony — all you need is a quality softphone solution. You won’t need to worry about installing and maintaining your PBX server anymore, either. Softphones make all calls over a standard internet connection.
Support Integrated Video Conferencing and CallingA top-tier softphone solution will have video calling integrated. Video calls are quickly gaining popularity. Ensure that your business is ready with the right softphone that already has integrated video calling.
Add New Lines As NeededAdding new lines is easy. Anyone with the right access level can create a new line. New employees should never be stuck waiting for their phones.
Increase Work Efficiency with User-Friendly ImprovementsSoftphones also improve your workflows with powerful features like call transfers, visual voicemail, notifications, file sharing, and more. These set of improvements are essential for call centers and businesses that heavily rely on making calls on a day-to-day basis.
Enhance Business FlexibilityBusinesses wishing to reduce operating expenses, become increasingly agile, and embrace a hybrid workplace can use softphones. Building and maintaining an in-house telephonic system is going to keep your expenses high. Conversely, softphones are billed based on real usage and the infrastructure is built elsewhere.

Unified Communications and Softphones Go Hand in Hand

Softphones can be considered the tip of the unified communications platform iceberg. Take the time to thoroughly understand every feature offered by the softphone and make sure that it has all of the softphone app features that your business is looking for.

Frequently Asked Questions

Softphone FAQs

  • Are Softphones Free?

  • Softphones can be either free or paid depending on the features and services needed. Free softphones typically offer basic functionalities suitable for personal or limited professional use.

  • What is the disadvantage of using a softphone?

  • A primary disadvantage of softphones is their dependency on a stable internet connection.

    Softphone applications cannot function without internet access, limiting communication capability, particularly in areas with poor connectivity.

    This reliance poses a challenge for users when consistent, high-quality internet service is not guaranteed.

  • Is a softphone the same as VoIP?

  • A softphone is a software-based component of VoIP technology, allowing users to make calls over the Internet from a computer or mobile.

    While VoIP is the broader system that also includes hardphones, a softphone specifically refers to the application that enables VoIP calls.

  • Why is it called a softphone?

  • It is called a “softphone” because it is software-based rather than a tangible (‘hard’) device like a traditional phone.

    “Soft,” short for “software,” signifies that the phone functions are provided through an application running on a computer or mobile device, utilizing internet protocol (IP) for communication.

  • Are Softphones Difficult to Configure?

  • No, softphones are no more complicated to install than any other application, both in desktop and mobile.

  • What Are the Basic Requirements for Using Softphones?

  • Fortunately, the requirements and limitations are quite minimal:

    • A computer or mobile phone.
    • A VoIP headset (or any speaker and microphone).
    • A VoIP (voice over internet protocol) service provider.
  • How can I start using softphones?

  • To use a softphone you will need a softphone app, an internet connection, and a VoIP SIP account.

    Most free softphone apps still need a connection to VoIP service providers for the minutes and the phone number, which comes with a cost.

  • How Can I Get the Best Quality when Using Softphones?

  • Headsets are recommended for softphone usage to guarantee the highest quality telephone calls. You can also use speakers and a microphone as alternatives, but that can result in the microphone picking up the voice coming out of the speakers.

  • How Do Softphones Look?

  • A softphone is a piece of software, so it looks quite similar to any other app that can make phone calls now. Additionally, early softphones were designed to mimic hardware phones, so there is plenty of overlap between how they look and feel — even if one is software and the other isn’t.
