Everyone is overloaded, it is a matter of needs to set priorities. Code 
is frozen now to prepare the release of 1.5.0, next version, which will 
use the http://sip-router.org project will add the onsend_route that 
makes possible to get access to the outgoing sip requests as well. With 
a bit of extension at that time, probably the entire siptrace 
functionality can be done only in the config file.

Daniel
