Introduction

The LanScape VOIP Media Engine™ is a complete SIP/RTP and media handling call engine development solution for the Microsoft Windows® family of operating systems. Tailored to meet your needs in stand alone applications and/or as part of client/server web based environments. The capabilities of the LanScape VOIP Media Engine™ are particularly suited for applications such as Soft Phones, Conference Servers, Interactive Voice Response systems, Telephony enabled web sites, PSTN Gateways, and software based PBXs. The LanScape VOIP Media Engine™ performs and excels brilliantly in Wi-Fi and 802.11 wireless ethernet environments. End user's who integrate the LanScape VOIP Media Engine™ into their architectures purchase a development specific license to deploy the technology.

If you've ever developed a network telephony application, you already know how demanding it is to get all of the details correct. From handling SIP protocol for session initiation to managing media streaming using RTP payloads. The details associated with session initiation, call states, real-time telephony data handling/streaming, network level programming, minimizing voice latency, and the inherent idiosyncrasies of the protocols are exactly the areas that will burn development time.

If this is your first time developing a network telephony application, be prepared for a journey. You will be faced with all of the same issues that seasoned telephony professionals deal with on a daily basis. Historically, it has been very difficult to develop all of the required telephony features you need without completely impacting your development schedule.

That is, until now. When you decide to integrate the capabilities of the LanScape VOIP Media Engine™ into your telephony design, you are on a fast track to success. By integrating the capabilities of the LanScape VOIP Media Engine™ into your development, you have instantly leveled the playing field and are now ready to complete with the big boys in the area of Voice over IP network telephony.

Instantly leverage LanScape's knowledge of Voice over IP telephony to your advantage. No longer do you have to intimately understand SIP and RTP protocols. Remember the days you spent digging through all those SIP and RTP protocol packets to find that little bug that caused big headaches? We feel your pain.

No longer do you have to develop software to manage call states. Forget about the format and rate conversion issues you once faced, it's now a thing of the past. Remember how difficult it was to minimize voice path latency? The list goes on and on.

When you integrate the LanScape VOIP Media Engine™ into your next telephony development project, you will be giving yourself the freedom to focus on the product you are trying to develop. You will be able to concentrate on your solution and forget about the underlying technology.
