Using Global Call to Implement
Call Transfer
The information in this chapter is technology independent, however it describes a method of call
transfer that is supported by IP technology only. For more specific information about
implementing call transfer on IP technology, see the Global Call IP for Host Media Processing
Technology Guide. For more specific information about implementing call transfer on E1, T1 and
ISDN technologies, see

11.1.1
Blind Call Transfer
In a blind call transfer scenario, party A transfers the call between A and B (Call 1) to a call
between party B and C without consulting party C. Party A places the primary call (Call 1) on hold,
directly dials the Party C address, and then disconnects from Call 1 before the second call
(Transferred-To Call, Call 2 - between B and C) is established. Party A may also request party B to
dial Party C's address and then disconnect from Call 1 after Call 2 between B and C has been
established.

(Transferred-To Call, Call 2 - between B and C) is established. Party A may also request party B to
dial Party C's address and then disconnect from Call 1 after Call 2 between B and C has been
established.
Before call transfer can occur, party A must be in a call with party B (Primary Call, Call 1).
Note:
In the scenario shown in Figure 34, party B initiates the transferred call to party C.
