Hi Iņaki,
 
  my understanding of the documentation is that mediaproxy can update the (Radius) DB in the
event of a missing SIP BYE, but Radius will do all other updates to DB accounting data. Does
that sound right to you? Do you have any documentation to the contrary etc?
 
cheers Andy.
 
 
Hi, I'm starting reading about CDRTool and as AFAIK:

- MediaProxy can update call media info directly into database (without using 
radius).
- OpenSer can log accounting in database (with "exrta-accounting").

So my question is: does CDRTool require a radius server? why exactly?

Thanks for any tip ;)
