What is VoIP, and how does it compare to PSTN connectivity?

The two major technologies dominating telephony systems are PSTN (Public Switched Telephone Network) and VoIP (Voice over Internet Protocol). PSTN is the traditional analog system that uses physical telephone lines, while VoIP is a digital technology that allows calls to be made over the internet. VoIP offers several advantages such as flexibility, cost savings, scalability, integration capabilities, and global reach. On the other hand, PSTN has the advantage of legacy, security, and control. Businesses are increasingly switching to VoIP for its numerous benefits and improved reliability provided by companies like Bandwidth.
