Developers have many toolkit choices to integrate IBM Lotus Sametime with a telephony system, but the Telephony Conferencing Service Provider Interface (TCSPI) is becoming the preferred option for Web conferencing applications. Follow this step-by-step tutorial to set up and experiment with building TCSPI telephony solutions outside of your production system.


Combining IBM Lotus Sametime with your company’s telephony system can be a natural marriage that enhances Sametime’s value as a collaboration tool. Integrate them well, and you can expect seamless support for voice applications within Sametime’s instant messaging and Web conferencing capabilities.
As a developer, you know that’s easier said than done. Each telephony system — and there are many of them — has its own integration requirements. This is largely what makes a Sametime/telephony integration project challenging, especially if you need to support more than one telephony system. Many integration toolkits exist, but how do you determine which one is right for your project?
Sametime has offered some form of telephony integration for years, but now it has a new toolkit addition called Telephony Conferencing Service Provider Interface (TCSPI). TCSPI enables Sametime customers and third-party vendors to seamlessly integrate their own telephony systems with the IBM Lotus Sametime server and client.
