The Dialogic® I-Gate® 4000 Session Bandwidth Optimizer (SBO) Core is a standalone system that enables cost-effective transport of VoIP traffic in 3G mobile and next-generation switching networks and offers significantly reduced CAPEX and OPEX associated with bandwidth and IP routing resources.
The I-Gate 4000 SBO Core leverages sophisticated in-house bandwidth and IP packet rate optimization technologies, while preserving the quality and reliability of the original VoIP traffic (for example, voice or fax). By combining high-quality VoIP payload optimization and Quality of Service (QoS) protection techniques, the I-Gate 4000 SBO Core can serve as a powerful CAPEX and OPEX savings solution for 3G mobile and VoIP wireline operators.
