NAT Traversal

10 reasons why businesses should incorporate NAT traversal into their VoIP or internet communication products

Increased penetration of broadband Internet is driving the adoption of voice over Internet Protocol (VoIP) both for consumer and business markets, propelling VoIP to be the preferred mode of communications. High quality multimedia communications along with rich presence, universal mobility and availability, and lower cost are some of the benefits VoIP brings to end-users. For operators, it promises new revenues from new and converged services, service bundling, increased customer loyalty, and lower capital and operation expenses by building and running a single IP-based network for all communications services.

Ironically, the main driving force behind VoIP adoption also poses one of the biggest challenges – VoIP calls do not work well in many broadband situations for NATs and Firewalls break VoIP. For this reason Eyeball Networks assembled a top 10 list of reasons why businesses should incorporate Eyeball’s AnyFirewall solution into their VoIP or internet communication products.
