7.15.2 Call Transfer
There are two types of call transfers:
„
Consultation Transfer:
The common way to perform a consultation transfer is as follows:
In the transfer scenario there are three parties: Party A = transferring, Party B =
transferred, Party C = transferred to.
•
A Calls B.
•
B answers.
•
A presses the hook-flash button and places B on-hold (party B hears a hold tone).
•
A dials C.
•
After A completes dialing C, A can perform the transfer by on-hooking the A
phone.
•
After the transfer is complete, B and C parties are engaged in a call.
The transfer can be initiated at any of the following stages of the call between A and C:
•
Just after completing dialing C phone number - transfer from setup.
•
While hearing Ringback – transfer from alert.
•
While speaking to C - transfer from active.
„
Blind Transfer:
Blind transfer is performed after we have a call between A and B, and party A decides
to immediately transfer the call to C without speaking with C. The result of the transfer
is a call between B and C (just like consultation transfer only skipping the consultation
stage).
Note:
The device doesn't initiate call transfer, it only responds to call transfer
requests.
