Hello,
the slides of the two presentations I gave at Amoocon 2010 are available online on event's site:
The SIP Router Project - Asynchronous SIP Routing - http://bit.ly/9Lm83T
Do your SIP routing in Lua! - http://bit.ly/c2uRYM
First talk went through the presentation of the project, features in 3.0 and devel versions, ending with short description of offered capabilities for asynchronous processing.
The second one focused on Lua API that can be used to do SIP routing, showing an example of asynchronous processing (as continuation to first talk): notifications to Twitter in case of missed calls using Lua API.
Cheers, Daniel
