The convenience, cost-savings, and advanced features of Voice over Internet Protocol (VoIP) are just some of the reasons why VoIP has far surpassed wired PSTN telecommunications.
VoIP apps let users access their virtual phone system from anywhere, on any device–including smartphones, tablets, and even desktop computers via a softphone interface.
VoIP capabilities aren’t limited to basic landline features like calling, voicemail, and call hold.
Today’s VoIP apps empower multichannel communication via voice and video calling, SMS/MMS text messages, virtual faxing, and even internal chat messaging. They also offer advanced call management strategies, call tracking and analytics, file sharing, and customer self-service.

Why Businesses Switch to Using VoIP Apps
Most companies switch to a business VoIP phone because virtual phone systems are much more cost-effective than traditional landlines.
The price of a VoIP system is a tiny fraction of the cost of a landline. Phone lines are cheaper, long-distance and international calling costs are less, and equipment and maintenance costs are nearly non-existent (all you need is a strong Internet connection to get your VoIP phone service up and running.)
Additionally, VoIP offers more features than traditional telephony ever could, including such as video chat, real-time analytics, and AI-powered voice transcription.
Another benefit of VoIP is that it is incredibly easy to scale. Adding more employees doesn’t require more equipment, as employees can use VoIP apps on their own devices with a BYOD policy.
Finally, VoIP solutions are easily integrated with other third-party business software like CRM systems and team collaboration apps.
How to Choose a VoIP App for Business
The VoIP app market is exploding–and therefore highly competitive.
The best VoIP app for your business will depend on the size of your business, your budget, the features that you require and want, and whether your business requires a customizable flexible solution (such as Vonage) or a more straightforward “out-of-the box solution” (such as 8×8).
Researching different VoIP service providers and reading user reviews is a great way to find the perfect platform for your unique business.
