IPFreedom enables end-to end IP Voice and Video by securely crossing network firewalls and NATs. Most notably, this great tool from Ridgeway enables seamless connectivity with no compromise to security or the overall integrity of the end-to end connection.

This tool can resolve your online videoconferencing or VoIP connection issues only if the technology you are utilizing utilizes the standard H-323 or SIP protocol. IPFreedom supports also the data-collaboration standard T-120 and all equipment and software that supports it.

Ridgeway IPFreedom is server software that works with existing security policies and is simple to install and manage. The IPFreedom server runs on Windows XP™ / Windows 2000 Professional™ or Server with Service Pack 2.

The solution requires no upgrade to existing firewalls and NATs, enabling easy and cost-effective deployment of real-time IP communications.

IPFreedom can be deployed as a site-wide solution, or it can be distributed to selected users. In either case, you remain the one to select authenticated authorized clients that will be able use the connectivity services enabled by IPFreedom.

IPFreedom is an effective solution for those of you who utilize hardware-based systems, such as Polycom ViewStations to software endpoints such as Polycom ViaVideo and NetMeeting.

IPFreedom is a software technology that enables IP voice and video communications that can be carried out without incurring in the typical issues created by the presence of corporate or private firewalls and NATs.

IPFReedom achieves this much needed feat neither by bypassing the firewall or NAT nor by requiring firewall/NAT software upgrades. IPFreedom does not compromise security in any way indeed.

Ridgeway solution not only provides connectivity for individual individuals connected to the network, but it can also allow an organization to share MCUs (multipoint conference units), gateways, etc., even though such equipment is maintained in a private and well secured state fully behind firewalls and NATs.

All of this functionality is achieved while keeping the firewall fully secure and completely closed to the world.

IPFreedom supports both SIP and H.323 protocols.

IPFreedom supports also Microsoft Windows Messenger since December 2002. Windows Messenger, which is included in the Microsoft Windows XP, is an integrated center for real-time voice and video conferencing, instant messaging, and online collaboration. With IPFreedom you can reliably utilize Microsoft Windowsw Messenger to go through a hybrid of network environments and devices and to conduct voice and video conferences reliably.

You do not need to open up ANY post on your firewall to make this system work.
With IPFreedom, inbound ports are never opened. Ridgeway’s technology uses only outbound TCP and UDP connections, even though the product enables calling in and out of the network.

IPFreedom is also firewall agnostic and does not care about the type or brand of firewall or NAT that you have in use.

Q: What if I am using a private IP address?
A: IPFreedom resolves NAT issues and allows users on different networks with private IP addresses to communicate.

To make its magic work IPFreedom uses only two authorized well-known ports,
2776 and 2777. As part of the IPFreedom technology, only two outbound ports are used even though multiple calls may be connected outside the secured network. No random ports are ever used.

IPFreedom employes a server-client architecture to perform its trick.
IPFreedom is composed of a server software that must be installed on an standard Windows-based server computer and of two types of IPFreedom "clients": The site client (for connecting multiple "endpoints") and the personal clinet (only for one individual).

The Site Client software runs on industry-standard computers deployed within a private network, protected by existing security infrastructure policies. The Site Client works by directing external voice, video, and data communication to the well-known boundary traversal ports (2776 and 2777) of a Ridgeway IPFreedom Server.

The site administrator controls which IPFreedom Server the Site Client should connect to, and connections are authenticated to ensure that service is available only to authorized sites. All real-time communication passes exclusively through authorized, outbound Client-Server connections using well-known ports through any number of intervening network boundaries.

The Personal Client is ideally suited to users who need to keep in touch while on the move – for SOHO deployments where Site Client might simply not be convenient. The IPFreedom Personal Client software runs on standard desktop PC or laptops, whether they be located within a private network, in home offices, or in hotel rooms or airport lounges.
