Hi Darshan,

The dirrence between Attended & un-attended call transfer is:

In Attended call Transfer(also called as Call Transfer with
Consulation), A calls B, then A calls C, establishes peer to peer
connection with C (During which B is in HOLD state), Informs C about B,
Then keeps C in Hold, Tranfers B to C, Then A comes out.

In Un-attended(Call transfer without Consulation), A will not establish
Peer to peer with C, simply transfers. 

I can forward you the detailed call flow in case you need it.

Regards,
Prveen
