Tekelec has a long history with SS7 and today have a strong focus on IMS and SIP-based solutions. Most of what they do isn't terribly sexy - routing, ENUM, signaling, messaging and traffic management - but it's core for any nextgen network. They have a lot going on with mobile messaging, and that's an area I'm particularly keen to learn more about.
Perhaps more importantly, this is a company that's doing quite well in a down market. Their stock price is off - no surprise there - but not nearly to the extent that most telecom vendors are seeing. They just had their Q3 results, which were quite strong, and the company is on track for $500 million in revenues next year. They're definitely doing a lot of things right, and that's reflected in a couple of recent news items. First, they were just named to the Forbes list of 200 Best Small Companies, and second, they were recently added to the Standard & Poors SmallCap 600 list.
