New RealTunnel provides support for SIP, H.323 and H.460 Firewall, NAT and web proxy traversal

Paradial announced RealTunnel 3.0 adding full support for H.323 and H.460.18/19 firewall, NAT and web proxy traversal.. By adding support for H.323 and H.460.18/19 to the existing SIP and protocol agnostic capabilities, Paradial offers a truly unique product in the market space.

As H.460 provides limited connectivity for H.323 communication, Paradial has extended the H.323 firewall NAT traversal capabilities to also include support for TCP and HTTPS relaying when needed in order for calls to be placed and received. This way maximum call completion rates can be achieved for both H.323 and SIP clients independent of location, including when on strict corporate networks. RealTunnel automatically detects the optimal transport mechanism for each call and achieves the best possible audio and video quality for the call at hand.

In addition to support for SIP and H.323, XMPP is supported through a SOCKS interface. Other protocols may be supported through the protocol independent media SDK.

“IP telephony manufactures, video conferencing vendors and telcos no longer have to use different firewall and NAT traversal solutions for various protocols and market segments. RealTunnel delivers connectivity for any IP telephony client on any network without any configuration or equipment replacement required. RealTunnel is ideal for residential and corporate services and always provides maximum call completion”, says Kevin Kliland, Product Director, Paradial.
