Press Release

LanScape Corporation delivers its fully scalable Voice and video over IP session and media proxy server software to the world wide VOIP marketplace.

Minneapolis, Minnesota - (January 6, 2012) LanScape Corporation announced this week that it will be offering it's general purpose scalable SIP proxy and scalable RTP media proxy server software solutions to the general world wide VOIP marketplace. With LanScape's scalable VOIP server software, you can deploy SIP/RTP voice and video VOIP domains and networks while at the same time overcoming all per-to-peer session and media issues related to traversing Network Address Translation (NAT) environments.

LanScape's VOIP server software consists of two primary server applications: The LanScape Centrex Proxy Server™ - A full featured SIP proxy server, and the LanScape VOIP Media Proxy™ - A high performance RTP media proxy. End users can deploy a single SIP proxy and one or more RTP media proxies as they require or multiple SIP proxies (sharing the same registrar database) with one or more RTP media proxies. The deployment combinations of SIP proxies and RTP media proxies are not limited in any way. Any scalable combination is possible.

The SIP Session Proxy:
LanScape Centrex Proxy Server™ is a full featured voice and video SIP compliant session proxy. Designed for all versions of Microsoft Windows. The Centrex Proxy Server™ software is responsible for the setup and teardown of voice and video VOIP call sessions and the management of the VOIP domain. Each call sesson the SIP proxy manages can have up to 128 media sessions defined which in turn can be proxied for full NAT traversal.

The LanScape Centrex Proxy Server™ is easy to deploy and use and incorporates an intuitive GUI interface and a series of simple configuration dialogs. The Centrex Proxy Server™ has many required and useful VOIP features such as: Real time call processing/logging, integrated Denial of Service (DOS) attack prevention, full control over network settings, programmable call processing time outs, integrated SIP registrar support, simple to complex sequential call routing capabilities, Global iNet™ user account login capability, supports one or more LanScape VOIP Media Proxies, integrated WAN and IP/NAT detection, Custom user Plug-in DLL to modify received and transmitted SIP protocol information (full C++ source code supplied), control over event logging and SIP message logging and full challenge handshake authentication using the MD5 algorithm for security.

Also of great importance is the ability of the LanScape Centrex Proxy Server™ to perform complex SIP protocol packet, IP address and port fix-ups. The Centrex Proxy Server™ automatically detects SIP protocol packet errors and attempts to correct SIP protocol packet information. With this capability, NAT traversal is possible and ill-behaving SIP devices can still be used in the VOIP domain. Until now, this complex capability has only been available in expensive 3rd party dedicated session border controllers and session boundary controllers. Now all you need is a single LanScape Centrex Proxy Server™ and one LanScape VOIP Media Proxy™ to achieve the same results. This will save thousands of dollars when deploying your next VOIP network or domain. Also, when you use LanScape's server products, media proxying is only applied to VOIP phone calls if it is absolutely needed to ensure the exchange of voice data.

The RTP Media Proxy:
The LanScape VOIP Media Proxy™ is a high performance voice and video RTP media proxy. This server software is used in conjunction with one or more LanScape Centrex Proxy Servers. The primary reason to deploy the media proxy is to overcome VOIP voice and video media related issues due to Network Address Translation (NAT) existing in the network environment. When you build your VOIP domain around LanScape's session and media proxy solutions, you are able to overcome all session (SIP) and media (RTP) issues related to NAT.

Also of importance is the fact that the LanScape VOIP Media Proxy™ server has been designed so that it is RTP media payload independent. This means that as new lower bit rate codec capabilities are used in your VOIP domain, your investment in your RTP media proxying capabilities remain unaffected. The LanScape VOIP Media Proxy™ server can handle any current and future RTP media stream or payload type.

Randal J. Ziegler, Chief Technical Officer at LanScape Corporation stated: "Our customers have continuously requested that we offer a full featured and simple NAT traversal solution that makes their VOIP network deployments fast, simple and easy. Our customer base had begun to develop a growing frustration with overly complex "open source" offerings and most of the other higher cost 3rd party solutions that are currently available.

They also needed a clean, scalable Windows based session and media NAT traversal solution they could use when they deploy their LanScape VOIP Media Engine™ developed products and services to their customers.

The product pilot programs we conducted in 2005 with a subset of our customers indeed showed us that we could achieve the required capability at a very favorable cost target.

With LanScape's VOIP server software, deploying a new scalable VOIP domain is truly easy. If you already know how to setup an email server, you will have no problem deploying your very own SIP/RTP VOIP domain or network. Actually, setting up a new VOIP domain is simpler.

One of our goals at LanScape is to make available VOIP solutions that anyone can use. We also want to create products that will generate enthusiasm for this technology and play a role in the next generation of VOIP capabilities that will eventually appear in the market.

The introduction of LanScape's VOIP server products to the marketplace further acts to level the playing field. You no longer have to procure a large team of telephony specific developers or contractors to develop and deploy your VOIP based product or service."
