Effective telephony solutions are necessary for any modern business. Irrespective of the business size, investing in the leading business telephony is needed by every service-based company. Modern additions like voice-over-internet protocol (VoIP) services enable businesses to operate remotely. However, the US VoIP business lines only touched  41.6 million by the end of 2018. 

Not even the big fishes, but the startups and small businesses are also investing in modern business telephony services. As a result, this specific segment will invest 15% higher in VoIP solutions by 2025. Moreover, the ongoing covid-19 pandemic further raises the issue of flexible remote working operations.

The markets of VoIP services are increasing, and hence multiple players are offering different services to global users. So, today we bring you a detailed review of the top three contenders in the business telephony solution providers. These are 3CX, FreePBX, and CallHippo. We will start by understanding their services independently and then check out a detailed  3CX vs. FreePBX vs. CallHippo comparison.
