3 Best Free Softphone Software

Published by in Call Center

Is your company looking to reduce costs related to business communication? If so, explore softphones that are cheaper communication tools than traditional phones.

Software phones, also known as softphones, can help reduce call costs significantly.

Your teams can use softphones to call (or receive calls from) colleagues and clients, primarily over the internet. This can help you avoid the high charges levied by telecommunication companies for long-distance calls.

You can also save on hardware costs since multiple team members can access the same softphone solution via virtual extensions on their computers or mobile devices.

However, if you’re unsure how softphones work and how these tools will integrate with your operations, give free solutions a shot.

We have scoured the web to create this list of the three free best softphone solutions available below and arranged alphabetically. Read more about our methodology here.

Softphone solutions can drastically reduce communication costs for your business and are also useful for employees who need to work remotely.

However, that doesn’t make softphones automatically right for you. If your business demands that you make simultaneous calls to multiple clients, then audio quality can be an issue. In such a case, you might need to upgrade to dedicated VoIP phone systems that include hard phones and offer better audio quality.

To ensure you’re investing in the right business communication tool, we recommend that you examine multiple software categories, including call center software, telephony software, and IVR software.
