Hello :
http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_att_xfer
I found this example seems not an "attended transfer" , rather
a consultation hold.
An ext 1527 --> call ext 1528 , then 1528 press "*3" , and keyin "1529#"
1527 into holding state listening music, 1528 and 1529 bridged
if 1527 hungup , all disconected , only on 1529 hangup , 1527 go back with 1528

In this scenario, Alice calls Bob. Bob places call on hold. Bob
calls Carol. Bob then disconnects with Carol, then takes the call
with Alice off hold. The call ends when Alice hangs up.

In this scenario, Alice calls Bob. Bob puts Alice on hold then calls
Carol to announce transfer, then places Carol on hold. Bob transfers
Alice to Carol which replaces the session between Bob and Carol.

Lee,
If you're going to use SIP then use the attended transfer feature of
your SIP phone we support both blind and attended transfers within the
confines of sip. If you would have pressed 0 the call would have been
turned into a threeway call. Then you could hangup and the transfer
would be complete. This feature is mostly for Analog and pstn phones
that don't have a native attended transfer feature.
