  1. Public Switched Telephone Network or PSTN is the traditional form of telecommunication. • It is also referred to as the Plain Old Telephone System (POTS). • This circuit switched public telephone network allows calls from landline phones.

  2. Telephone lines • Fibre optic cables • Switching centres • Cellular networks • Satellites • Cable systems

  3. The telephone set converts the sound waves into electrical signals. The signals are transmitted through cables. • The central office routes the calls through fibre optic cable in the form of electrical signals. • The electrical signals are routed to a terminal. Thereafter, the terminal routes the call to the appropriate telephone number. • The telephone set converts the electrical signal back to sound waves which the receiver hears.

  4. Cost : • The cost of PSTN is much higher than that of VoIP. • The cost for setup and installation of VoIP Phone System is less than PSTN charges. • The call cost in PSTN service depends on the distance where the local calls are cheaper and the mobile or international calls are costly. • In VoIP, the cost is low due to the minimum requirement of hardware.

  5. Productivity: • Using VoIP Technology results in an increase in productivity. • VoIP Phone system helps the employees to communicate with one another in a more effective way. • VoIP Technology provides the opportunity to work from home or on-the-go.

  6. Security: • Though because of dedicated phone line PSTN may seem more secure but phone lines can be tapped. • The security for VoIP Calls mostly depend on the internet connection and the VoIP Service Provider. • Many VoIP Services offer encryption and 2-step authentication and many other security protocols to protect the privacy of the user or the organisation.

  7. Maintenance: • The maintenance of Public Switched Telephone Network is a costly affair. • VoIP Technology is based on software and requires minimum maintenance. • Regular updates of software not only removes any glitches but also at times adds new features.

  8. Scalability: • The option of scalability is a big plus point for VoIP. • Scalability is however difficult for PSTN systems. Additional cost and hardware are required for any necessary changes. • Accommodating according to the business size and requirement is easy in VoIP Systems.
