The traditional Public Switched Telephone Network (PSTN) is turning off
The era of the traditional Public Switched Telephone Network (PSTN) is approaching its end as digital technology continues to replace the legacy system of wired telephony. In various jurisdictions, the PSTN shutdown, initially planned for December 2025, has now been rescheduled to take place in January 2027, marking a significant shift in telecommunications history.
Since their inception in the 1880s, telephone exchanges—built on physical infrastructure—have formed the backbone of global communication by routing calls through switches and circuits. These exchanges have been essential to connecting homes and businesses for over a century.
However, with advancements in digital technology, traditional landlines are giving way to modern communication solutions. The transition involves a move towards digital networks, including wireless and cloud-based systems that leverage Internet Protocol (IP) and Voice over Internet Protocol (VoIP) technologies. This shift promises more flexible and efficient communication capabilities for both residential and commercial users.
