PSTN (Public Switched Telephone Network)
The traditional circuit-switched telephone network.
Definition
The Public Switched Telephone Network (PSTN) is the traditional global telephone network that uses circuit-switched connections to carry voice calls. It includes landlines and legacy mobile networks.
In Depth
While PSTN remains widely used, businesses are increasingly migrating to VoIP and SIP-based systems for lower costs, better scalability, and integration with digital communication platforms. PSTN-to-VoIP gateways allow hybrid setups.
Lodgestory's telephony integrations bridge PSTN and VoIP through partners like Tata Tele and Airtel, enabling businesses to manage traditional and digital voice in one platform.
