Did you know that only 7% of participants get on teleconferences via VoIP? A 2017 survey also concluded that 70% of conference calls are taken from their landlines that work on PSTN.
VoIP’s failure to find relevance in business communication is due to the poor audio quality on conference calls and dropped calls. The participant’s preference for non-VoIP and PSTN audio conferencing solutions also underscores how critical audio quality is for enterprise conference calls.

The problem with VoIP Conference Calling
VoIP (Voice over Internet Protocol) is a wireless telephony system in which the calls are connected through the Internet network. When you make a call through VoIP, the voice information is converted into individual network packets. These countless packets travel across the Internet to reach their destination.
In using VoIP to get on a conference call, there is always the risk of a power outage, which can disrupt the flow of the call.
While the emergence of broadband Ethernet and WiFi, call connectivity and audio quality have improved by a tremendous scale, but VoIP still doesn’t quite measure up to good old PSTN.

Why is PSTN the more reliable option for conference calls?
PSTN (Public Switched Telephone Network) is a traditional telephony system, which is also referred to as Plain Old Telephone System (POTS). It works through circuit switches and dedicated lines.More than 55% of conference calls involve the sharing of business-critical information, and audio quality as such is extremely important. And, PSTN lines guarantee crystal clear audio, as the voice is transmitted over a dedicated channel that physically connects the two ends. PSTN audio conferencing also provides an uninterrupted communication link even during a power outage. This is because phone jacks are powered by the PSTN provider.
