Paradial Launches RealTunnel 4.0 Firewall/ NAT Traversal Solution

By SIP Trunking Report Contributor

Norwegian standardized IP connectivity and security solutions provider Paradial AS reportedly has announced the availability of its latest firewall/ network address translation traversal solution, RealTunnel 4.0, along with significant new features.

The new release will provide support for SIP trunking, cross enterprise communications and customer-premise deployments of SIP and H.323 PBXs and servers.
According to Paradial, RealTunnel is a complete “network address translation” and firewall traversal solution that enables secure and high quality media solutions to work across IP networks. This open, SIP and H.323-compliant solution helps SIP and H.323 clients to work with virtually any firewall and network in a non-intrusive way and without any reconfiguration required.
The RealTunnel solution encompasses a client and server. Both are standards based and may run independently of each other. It supports latest ICE, STUN, and TURN drafts, in addition to H.460.18/19 and HTTPS tunneling. It helps in reducing the cost of SIP and H.323 deployments. It provides cost savings by allowing real-time audio and video communication applications across organizational and network boundaries, such as the Internet and corporate intranets.
The latest release, RealTunnel 4.0 features TLS support, which expands RealTunnel’s capabilities in strict enterprise security environments. It now works with PBXs, SIP registrars and H.323 Gatekeepers, which are not available publicly, but located on the inside of a corporate LAN.
Moreover, RealTunnel Firewall/NAT supports all client features, such as presence, chat, voice, video, application sharing, multiparty conferencing, regardless of network. It can be configured and setup as a VoIP SSL VPN (virtual private network).  It is also ideal for P2P (peer-to-peer) and music/content distribution, says Paradial.
Officials with Paradial said in the release that RealTunnel 4.0 will help organizations to overcome the inherent conflict between security and accessibility, which usually results in voice and audio traffic being blocked unintentionally by firewalls, NATs and web proxies.
"The release of RealTunnel 4.0 demonstrates Paradial’s continued commitment to provide the unified communications, videoconferencing and VoIP industry with solutions that help organizations overcome the NAT traversal challenge,” Espen Skjæran, CTO for Paradial, said.
By leveraging RealTunnel UC, videoconferencing and VoIP solutions can be implemented as well as accessed by end users anytime anywhere without modifying firewalls or changing existing infrastructures, said company officials.
