What is PSTN

PSTN stands for Public Switched Telephone Network. It refers to the traditional telephone network that uses copper wires to transmit analog voice signals. PSTN is the oldest and most widely used telephone network in the world, and it is still in use today, particularly in rural areas and developing countries.

PSTN uses a circuit-switched architecture, which means that a dedicated connection, or circuit, is established between the caller and the recipient for the duration of the call. This is different from newer technologies such as VoIP (Voice over Internet Protocol), which use packet-switched architecture, where data is broken into small packets and transmitted over the internet.

PSTN is known for its reliability and high-quality voice calls, but it is becoming less popular as more people are turning to VoIP and cellular services for their communication needs. PSTN networks are still used for many traditional phone services, including 911 emergency calls and fax machines, and also for some specialized applications such as credit card machines, burglar alarms, and elevator phones.

What is VoIP

VoIP stands for Voice over Internet Protocol, it is a method of making telephone calls over the internet. VoIP uses the internet to transmit and receive phone calls. This allows users to make calls from anywhere with an internet connection, whether it be a computer, smartphone, or VoIP-enabled phone.

VoIP uses a digital signal to transmit voice and other data, such as images and text, over the internet. This method converts the voice into a digital signal that is then sent over the internet and then converts it back to an analog signal on the other end to be played through a speaker.

VoIP is known for its cost-effectiveness as it eliminates the need for traditional phone lines and long-distance charges, it also allows for a wide range of features such as voicemail, call forwarding, and call waiting. VoIP also supports video calls, conferencing, and other collaboration features, which makes it popular among business and remote workers.

VoIP service can be provided by a variety of providers, such as telephone companies, internet service providers, and software companies. Some popular VoIP providers are eztalks, Skype, Zoom, Google Voice, and WhatsApp.

Why is VoIP better than PSTN for business

VoIP is generally considered to be superior to PSTN in several ways:

1. Cost-effective: VoIP eliminates the need for traditional phone lines and long-distance charges, which can save businesses and individuals a significant amount of money.

2. Flexibility: VoIP allows users to make and receive calls from any location with an internet connection, whereas PSTN is limited to a specific location and phone line.

3. Advanced Features: VoIP offers a wide range of features such as voicemail, call forwarding, call waiting, video calls, conferencing, and other collaboration features which is not available on the PSTN network.

4. Scalability: VoIP allows for easy scaling of phone lines and features as needed, whereas PSTN may require more time and effort to make changes.

5. Quality: VoIP uses a digital signal to transmit voice and other data, which can provide a higher-quality call than PSTN, which uses an analog signal.

6. Integration: VoIP can be integrated with other communication tools such as email, instant messaging, and video conferencing, which allows for a more unified communication

Overall, in a modern communication system, VoIP is the first choice of business, from small to large size company. If your company still using PSTN, it's time to consider switching your old PSTN to a modern VoIP system.
