Hello, I'll give a lecture, focusing on FreeSWITCH, as well as comparing it with other open source pbxes/switches/proxies. The talk will have a brief overall of the available software choices for the most common cases, but the main goal is to spread the word and show what this project is capable of. That'll happen in "Faculdade Impacta de Tecnologia" (Impacta college of Tecnology), which exports technology and teaching methodologies to some countries, etc. The contents of the talk aren't defined yet, I just told them the idea and it was very well welcomed. I would like to show the developers' perspective, as well as some real use cases, that's why I ask you guys to say whatever you think it's worth about those topics. There will be live examples of applications, I'd also be grateful receiving ideas for that. Thanks, Arnaldo
