can anyone guide me to where in DevNet or Cisco WEB site I can download a document showing list of IP phones and Cisco sofphones that support built-in-bridge (BIB).
I don't think such a list exists. There is a CTI supported device list but not a list of phones with BIB. You probably need to go to data sheet of each device you plan to use to find out the supported feature list.
If you are using any of the recent phones, most likely they all have BIB
