3.5 Call Transfer
An established call can be transferred to another internal extension. There
are two types of call transfer, (i) Blind transfer (ii) Consultation and
transfer.
Blind transfer (Unannounced transfer):
1. Assume A, an outside party called an internal extension, B. While Aand B
are talking B decides to transfer the call to another extension , called C.
2. To transfer the call, B presses flash/recall. At this moment Extension B
hears dial tone and the outside party hears Music on Hold. Then B dials
xx , where xx is the extension number of C.
3. If the operation was successful, B will hear ring tone and hangs up at
once.
4. C rings, andAhears music while waiting for the connection.
5. C lifts the handset and answers the transferred call ofA.
6. C also can transfer the call to another extension in the similar fashion.
7. In the step 4, if the C does not reply within 25 seconds, the system rings
back B. If B does not answer within 30 seconds, the call gets
disconnected.
Consultation transfer:
1. Assume B is an extension. A is an outside party. A called B and A and B
are talking. B wishes to consult C and then transfer the call.
2. B presses flash/recall, hears dial tone, dials the extension number of C.
3. If all of the above operations are correct, B will hear ring tone. Extension
B does not hang up in this case.
4. While C rings,Ahears music while waiting for the connection.
5. C lifts the handset to talk to B. A still hear music while waiting for the
connection.
6. At this time either B or C can hang up. For example, if Bhangs up first, C
gets connected to A. If C hangs up, B gets connected withA.
7. In the step 4, if the C does not answer within 25seconds, the system calls
back B. At this time, B can pick-up the call and speak to A. If B does not
respond within 30 seconds, the connection disconnects automatically.
