Calling Card Software/softswitch 🎯 Must Watch

: To maintain profitability, the softswitch uses Least Cost Routing (LCR) to select the cheapest available provider for the destination country. Key Features for Providers

: The provider installs the software on their own servers, offering maximum control and security but requiring significant hardware investment.

: Providers can set complex rate tables, including connection fees, maintenance fees, and different rates for peak/off-peak hours.

A calling card softswitch is a centralized VoIP platform that manages the routing, billing, and authentication required to operate a calling card service. In essence, it acts as the "brain" of the operation, connecting traditional telephony networks with modern Internet Protocol (IP) networks to facilitate low-cost long-distance communication. Core Components and Functionality

: Once a user dials the access number, the softswitch triggers an IVR system to prompt the user for their PIN and the destination number.

: The AAA (Authentication, Authorization, and Accounting) module checks the user’s balance. It ensures the PIN is valid and determines how many minutes are available based on current rates.
