Press Release: Scalable SIP Proxy and RTP Media Proxy for NAT traversal
Press Release: LanScape Corporation delivers its fully scalable Voice
over IP session and media proxy server software to the world wide VOIP

Product URLS:

Minneapolis, Minnesota - (January 3, 2006) 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 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)

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

The SIP Session Proxy:
LanScape Centrex Proxy Server™ is a full featured SIP compliant
session proxy. Designed for all versions of Microsoft Windows. The
Centrex Proxy Server™ software is responsible for the setup and
teardown of VOIP call sessions and the management of the VOIP domain.

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 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 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."
