This is due to the way that analog signaling works... the fxo port has
no way of telling when the remote party actually answered the call.  If
you were to call out over a PRI line instead, you'd see that your CDR
records would show when the call was actually answered by the remote
party, as PRI lines give Asterisk that information.
