[Asterisk-Users] How does Asterisk choose the CDr backend to use?

[David Filion]

Hi,

I'm trying to understand how Asterisk chooses the backend it's going to 
use for storing CDRs.  For example, if PostgreSQL, MySQL, and FreeTDS 
are installed, how does Asterisk know which one to choose? Does it 
choose which ever one is configured are forget about the rest or will it 
send a CDR to each configured backend?

(I'd just go ahead and try it but I don't have an Asterisk server I can 
"play" will right now.)
