Yes, it is possible to do call transfers with Asterisk. Some of the features may be seen here:

How you transfer depends more on the endpoints. For example, the X-Lite softphone from CounterPath handles the transfer as a set of SIP messages. While with a Sipura ATA and an analog phone you may do a ‘flash-hook’ method of attended transfers.
