NAT traversal

Passing through network address translation (NAT) to reach a user. NAT hides private IP addresses from the public Internet; however, voice over IP (VoIP) and videoconferencing calls that originate from outside the network must locate the user's IP address. See STUN, UPnP and NAT.

However, the decision may impact the longer-term earnings potential of the patent licensing program, especially for NAT Traversal patents.
The IETF has previously published a third NAT traversal specification:
EdgeProtect provides SIP and H.323 local call control or secure proxy support for external call control elements, and enhanced media handling features include shortest path media routing and media relay when NAT traversal is necessary.
To support symmetric NAT traversal, Sym Teredo slightly adapts the network router without modifying the Teredo server.
AnyFirewall Engine v9.6 provides support for devices running Android, iOS, Linux, OS X, VxWorks, Windows, Windows 8, and Windows RT operating systems, and can be deployed in conjunction with Eyeball's AnyFirewall Server v9.6 and AnyConnect Gateway for a complete end-to-end connectivity solution providing guaranteed firewall and NAT traversal, or be combined with other third-party, standards-based products.
Aligning with software-only architectures, the Mediant Software SBC integrates smoothly into both virtualized and non-virtualized environments, providing essential session border control functions such as SIP and Media normalization, NAT traversal, authentication, encryption, denial of service protection, SLA enforcement and routing.
An advanced near-end and far-end NAT Traversal feature set negates the need for Virtual Private Network (VPN) connections.
