Andrew Prokop -- Andrew Prokop has been heavily involved in the world of communications since the early 1980s. He holds five United States patents and was on the teams that developed Nortel's carrier-grade SIP soft switch and SIP-based contact center. Andrew is an active blogger and his widely read blog, SIP Adventures, discusses every imaginable topic in the world of unified communications. He is just as comfortable writing at the 50,000 foot level as he is discussing the subtle nuances of a particular SIP header. Andrew can be found on Twitter at @ajprokop.
