Firewall and Nat Traversal SDK for VoIP

Firewall and NAT traversal is a key issue behind the wide spread adoption of VoIP. The VoIP call failure rate is 310 time higher than traditional lines. Up to 24% of customers cancel VoIP subscriptions, with the number one complaint being failed VoIP call completion.

Eyeball AnyFirewall Engine is a software development kit which enables 100% call completion of VoIP call through firewalls and NATs on any application, service or device.
 

The Eyeball AnyFirewall Engine offers:

NAT Traversal Most comprehensive implementation of STUN, TURN, and ICE, plus optional features such as UPnP gateways and HTTP tunneling through web-proxies.
Firewall Traversal Automatic selection of transport modes (UDP or TCP), and transparent translation of UDP to TCP when using TCP relaying.
NAT Traversal Supports symmetric RTP and smart keep-alives for signaling and media connections.
SIP Traversal Multiparty calls with hybrid UDP, TCP and HTTP streams.
NAT Traversal Traversal for voice, video, instant-messages and file-transfer.
Firewall Traversal Minimized call completion time by pre-fetching and caching candidates.
Firewall Traversal Simple C/C++ API familiar to TCP/IP socket programmers.
Firewall Traversal Works with 3rd party SIP/XMPP stacks & voice/video engines.
Firewall Traversal PC and embedded system support including Microsoft Windows, Linux, and Windows Mobile.

Standards-Based Firewall & NAT Traversal
Eyeball AnyFirewall Technology combines IETF standards STUN, TURN and ICE, with the company's own adaptations and innovations to deliver the best possible Internet communications experience for subscribers. This unique approach addresses the shortcomings of today's traversal alternatives and ensures your application or device guaranteed interoperability with existing third-party components and services.

Highest Peer-to-Peer Media Transport
Beyond the AnyFirewall Engine's traversal capabilities, Eyeball ensures VoIP and IP video calls connect using a peer-to-peer UDP as often as possible using STUN, ICE and in some cases Universal Plug and Play (UPnP). For service providers, this means better scalability and less infrastructure and operational costs combined with lower latency times. When peer-to-peer transport is
not possible, it falls back to TURN-mode using UDP, TCP or HTTP tunneling.
