Natpass 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.

In addition to nat traversal, security is another important issue addressed by NATPass™. DOS, DDOS, fast and slow attacks can be controlled. NATPass™ protect  the Proxy and Registrar server from malformed SIP packets and Avalanche Restart effect as described in RFC5390.

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.
