I do now know your setup but you only need to add some extra columns to your radacct table. Except for the time required to apply the sql changes (your table will lock and you cannot write to it) I am not aware of any impact on a standard freeradius installation.

Ok, it means that I'll just make the RTP pass through mediaproxy by 

enabling the use of it on non-NATed UA's. Just a question, I have an 

existing RADIUS accounting setup, would there be a problem if I 

implemented the accounting feature of mediaproxy? I'm afraid because 

written in the docs in the distro i need to patch the radacct table, 

will it affect the existing one or alter something?

Thanks,
