The log shows that your system (dialplan of trixbox) is not doing anything 
with the call. It is not put into 'ringing' (to signal the caller alert) nor
it is answering it. So the call get released after a timeout (this timeout 
depends on the line and provider).

You should ask trixbox guys what is happening here.
