NAT Pass™ Solution

NATPass™ is a VoIP NAT Traversal solution - Session Border Controller that allows voip sessions succeed when one or both voip endpoint devices connecting such as phone adapters, gateways or IP phones, are in a Natted network. NATPass™ will perform media path optimization (MPO) and will make media stream flow directly between endpoints.

NATPass™ Firewall Controller is designed to be a cost effective and simple solution for ITSP and VOIP service providers to deploy their network with a minimum of support and intervention on the customer premises side and totally automates the NAT traversal process. NATPass™ is compatible with any SIP compliant endpoint and server and can traverse Full cone NAT, restricted cone NAT, port restricted cone NAT and symmetric NAT.

By design, NATPass™ is not a multi-protocol solution but is built and optimized for SIP to increase its overall performance, reliability and ease of maintenance. NATPass™ is designed to work as an intermediary between endpoint devices such as SIP devices (Hard, Softphones, ATAs) and SIP Proxies also known as Registrars. NATPass™ provides great scalability at the lowest cost.
