In business promotion a company has to find proper communication lines be it through social media, blogs, web conferencing, Skype or good old fashioned phone calls. Proper communication helps in relaying information to and from prospective customers and it also improves efficiency by facilitating internal communication.

The two business phone systems available to small businesses are VoIP (Voice over Internet Protocol) and PSTN (Public Switched Telephone Network). Internet communication technology and cloud technology is used by VoIP while PSTN uses landlines. To help you find the right phone system best suited for your business we prepared the following pros and cons of the two systems.


VoIP has numerous features that make it more suited for businesses. For starters it includes features such as call forwarding and voicemail services.

Voice messages can also be converted to email messages, and a business can hold web conference with people all over the world. These features are not present in traditional lines such as the PSTN.

VoIP provides a convenience and improved user experience for both the business and customer. For instance it shows the call log of all calls and help address concerns raised by customers in a timely fashion. This means better customer service and sales. It is an efficient system that is detailed with clear timelines, it cuts cost and is portable. The bottom line is that VoIP is inexpensive compared to PSTN.


The cons of VoIP are that without an Internet connection it can’t work, slow Internet will affect it considerably and will lead to latency in information sharing and communication.

Power outages will affect it a great deal as it won’t work without power so it’s advisable to have a backup power generator.

It can also suffer attacks from viruses and other malware.The decision to choose either should be undertaken after adequate consideration between both systems.
