NAT Traversal

Conclusion

NAT devices and firewalls are major barriers to widespread adoption of VoIP, and IETF work STUN, TURN, and ICE provide an excellent methodology to address this issue. Unfortunately, ICE is a very complex methodology. Internet engineering experts at IETF have taken more than 6 years to develop it. Real implementation requires considerable insight and experience to get it right. Eyeball has invested many years to develop its technology, and its NAT traversal technology has been field-tested for more than 5 years. If you want to integrate ICE in your products and services, and are working with time-to-market and development cost constraints, getting the NAT traversal solution from technology experts at Eyeball may be your best option. Otherwise you may risk going into a prolonged cycle of development which may cause your project to go out of budget and delay your product launch.

Eyeball provides comprehensive and award-winning NAT-traversal solutions comprising two products: (a) AnyFirewall Engine - a feature-rich NAT traversal SDK incorporating ICE, and (b)STUN TURN Server - a carrier-grade STUN and TURN server. VoIP application developers, device makers, and service providers can now integrate and deploy these solutions into their products in order to guarantee VoIP and video call completion across NATs, firewalls, and web proxies.
