B is the application server here? Or B is a separate UE just like A, C and
app server is sitting in between? Please clarify.

Generally REFER is used for call transfer.

Hi,
I am a newbie in SIP. We are using web logic sip server as B2BUA.
 
I am having problem implementing call transfer. Call is established between
A and B
B is trying to transfer A to C. Call is established between B and C.
Call leg to A and Call leg to B exists in one application session and a call
leg to B and call leg to C exists in another  sip application session.
Now what the B2bUA (app running in weblogic sip server) should do to
establish call between A and C
 
Thank you. 
Naga
