Introduction

The LanScape Centrex Proxy™ Server is a full featured voice and video SIP proxy server. It allows you to easily setup and deploy your very own voice and video VOIP telephony networks or domains. You can deploy a single proxy server to handle your VOIP network or deploy multiple servers in a load sharing environment to handle large call volumes as your VOIP network grows. This is possible due to the integrated registrar capability which allows you to use a single registrar database or a shared centrally located registrar database.

The Centrex Proxy™ Server can be deployed in the global IP address space or within your protected IP network without sacrificing any globally accessible VOIP functionality or connectivity whatsoever. It supports a myriad of integrated functionality which will allow you to tailor your VOIP network or domain as you require.

If you deploy the LanScape Centrex Proxy™ Server in conjunction with one or more LanScape VOIP Media Proxy servers, you have a full featured, fully capable infrastructure that will allow you to handle all network environments. Specifically designed to overcome the problems associated with Network Address Translation (NAT) and port translation, you have a ready made session and media proxying solution that will get your VOIP phone calls connected every time. When properly configured, LanScape's Centrex Proxy™ Server will perform complex SIP protocol packet IP address and port fix-ups. These fix-up operations are required to correct all of the SIP protocol problems that are introduced due to NAT being deployed in the network environment.

Now, here is a very important point: With this solution, you no longer need to deploy expensive 3rd party session border controllers or session boundary controllers. All this capability is available to you in your familiar Microsoft Windows environment as a completely software based solution. Get ready to say goodbye to that antiquated dedicated VOIP hardware.

Features

Designed for the Microsoft Windows® family of operating systems - Versions 2000/XP/2003/Vista.

This product includes a fully functional LanScape Service Manager™ Suite install package and license.

SIP inter-op tested to perform superbly with any other SIP 2.0 device or software. Verified interoperability with SIP products from Cisco, Avaya, Swissvoice, Grandstream, Polycom, Snom and many, many others.

Supports both voice and video and any other generic media streams. Up to 128 media streams can can be defined in any one SIP session.

Supports peer to peer instant messaging using SIP MESSAGE packets.

Available in three product configurations: Personal, Professional and Enterprise.

Real time event logging to a log file and to the GUI.

Full control over the network configuration (IP address and SIP port, domain name, Max SIP message length, Router/Gateway IP address, etc).

Denial of Service (DOS) attack protection built in.

Configurable call processing timeouts.

Can be deployed using a multi-domain, shared regisrar database. This allows you to deploy as many Centrex Proxies as required and still allow all your users to call each other simply by dialong destination user agent names or numbers. A great solution for creating a large VOIP phone system.

Fully integrated registrar capability. Use the internal proprietary registrar database support for simplicity and ease of use. Alternatively, use an external registrar database (Microsoft Access, SQL, MySql, etc). If an external registrar database is used, multiple proxies can share the database for large VOIP deployments. Registrar presence events using SUBCRIBE/NOTIFY are supported.

Full user Authentication supported. Authentication information can be local to the proxy or retrieved from a centralized remote authentication database. OCBD database support is used so you can use any database back end you desire. Perfect for provisioning user account. Example Microsoft Access and MySQL databases included.

Configure static registrar entries. Acts as an "always available" local directory.

Perform complex sequential call routing tasks. Route calls to any location anywhere and in any order. Call routing supports regular expression syntax if desired. Route calls to other SIP endpoints without having the endpoints register. Perfect for routing calls to PSTN gateways, Asterisk PBX or any other VOIP element.

Deploy with one or more LanScape VOIP Media Proxy™ servers to obtain a complete session and media handling solution not previously available. Media proxying is very important in overcoming peer to peer media issues introduced by NAT network elements. When using media proxying, call media is load shared with all available media proxies. Highly recommended. LanScape media proxy solutions also solve the dreaded "media deadlock" problems other products face.

Fully automatic and configurable WAN IP address monitoring and detection when deploying the Centrex Proxy Server™ inside of your private network. Includes support to allow you to publish the WAN IP address, private IP address, proxy server SIP port and domain name to any web server using HTTP POST. A perfect solution for those who use dynamic DHCP services to access their VOIP domains.

Supports a custom plug-in DLL. With this "user developed" custom plug-in DLL and API, you have the ability to alter all received and transmitted SIP protocol data. The custom plug-in DLL API will also allow you to be notified of special call related events (call start, call terminate, etc). There are many uses for this capability such as: SIP message filtering, SIP message logging, getting badly behaving SIP devices to interoperate properly. The list is endless. A complete example custom plug-in DLL with full C++ source code is included. Requires Microsoft Visual C++ 6.x or higher. The example plug-in that ships with the server allows you to echo all SIP traffic to an external SIP message log server (also included).

Full event logging: Enable/disable logging error tone for errors. Log proxy errors, warnings, informational messages, registration activity, and all call related events. Events can be logged to the server's GUI and to a log file.

Log all SIP message activity to a log file.

Full challenge handshake authentication using the MD5 algorithm. Extremely secure since no password information is ever sent over the network. Configure the authentication domain and nonce expire time. Define a single user name and password for your VOIP domain or multiple user names and passwords for each user. Enable/disable authentication as it applies to the following SIP message types: REGISTER, INVITE, BYE, SUBSCRIBE and NOTIFY.
