Flash calls: New Authentication Channel For MNOs

February 16, 2024 4:49 pm Published by

Flash calls are emerging as a new challenge for mobile network operators (MNOs). These calls provide a means of authentication similar to SMS one-time passwords but are more cost-effective. However, they pose regulatory and revenue challenges for MNOs, who may not receive payment for zero-duration calls. Despite the controversy, flash call detection is crucial for MNOs to maintain control and security in their networks. Cellusys offers a Voice Firewall solution that provides real-time visibility and control over calls, ensuring network integrity and customer protection against flash call fraud.
