Yes, you can.  Just turn on threewaycalling and transfer in
zapata.conf.  Flashhook, dial the number, talk (if you wish) to the
person you've just dialled (without the caller you're transferring
hearing).  If you flashhook again, you'll have a threeway call; if
you simply hangup, the call will be transferred.
