[Asterisk-Users] Asterisk CDR

[mmiranda at americatel.com.sv]

Hi, im using asterisk for a voip (sip) solution, so i dont have any
zap/e1/t1 card and works great, but..., i have customers complaining that
the cdr begins the accounting of the call just when the phone is ringing and
not after the user have picked up the phone, i have verified this, is this
normal or expected?
How can i change this?, the switch guys are telling me that it must be a "B
answer" config somewhere but i coudnt find it in sip.conf, the customers are
paying us lots of second of "connection time" and they are not very happy
with this,
thanks
