Session Border Controller (SBC) Market Dynamics

DRIVER

Rising demand for secure cloud-based VoIP communication.

The rise of digital communication has pushed enterprises to shift from legacy telephony to SIP-based systems. In 2023, over 320,000 enterprises transitioned to cloud-based VoIP platforms. This transition creates demand for SBCs to ensure quality of service (QoS), manage signaling, and maintain session integrity. With over 89% of corporate voice traffic being IP-based by Q4 2024, the need for scalable SBC solutions has soared. This shift is further supported by over 44 countries mandating IP call monitoring and security features that are natively supported by SBC infrastructure. Additionally, 5G rollouts in over 70 countries necessitate SBCs for real-time voice continuity and low-latency packet flow control.

RESTRAINT
