Abstract:
In one embodiment, a first end device associated with a first user and a second end device associated with a second user may be participating in a call. During the call, the second user may wish to transfer the call to a third user. The second user has the choice of using a blind transfer or a consult transfer. In one embodiment, a gateway determines interworking information that is needed to interwork an H.450.2 message for the H.323 protocol to a SIP REFER message, and vice versa, to allow the call transfer.
