Question 9

Refer to the exhibit.

APSC(config-telephony-service)# transfer-system full-consult

What will happen to a call that is transferred when no second line is available?

A. It will fall back to a full-blind transfer.
B. It will be transferred without consultation using H.450.2 standard methods.
C. It will fall back to a blind transfer for nonlocal consultation or for a nonlocal transfer target.
D. It will be transferred without consultation using the proprietary Cisco transfer method.

Answer: A


The full-consult parameter will perform call transfers with consultation using second phone line if available and fallback to full-blind if second line unavailable (full-blind: Perform call transfers without consultation). For example, you are talking to Mr.A but you want him to speak with another person, Mr.B, then you can press the “Trnsfer” softkey (1st time). After hearing another dial tone, you can dial Mr.B’s phone number waiting him to answer the phone.

At this time, if your configuration is “full-consult” then you can continue speaking with Mr.B until you press “Trnsfer” softkey a second time. This will drop you out of the conversation and let Mr.A and Mr.B speak with each other.

If your configuration is “full-blind”, the phone will automatically transfer the call right after you have dialed Mr.B number and you don’t have a chance to speak with Mr.B before transferring your conversation. This configuration does not require you press the “Trnsfer” softkey a second time.

But the “full-consult” method can only work when the second line is available, if not, it will fall back to “full-blind” method.

(Notice: “Trnsfer” is the text on your phone, not “Transfer”)
