A. B. C. D. E. F.AC.
The CallBack softkey is a feature in the Skinny Call Control Protocol (SCCP) that allows a user to request a call back when the called party is busy or not available. The CallBack softkey appears on the phone display when the call is in certain SCCP call states.
Out of the given SCCP call states, the two that support the CallBack softkey are:
A. On Hook: In this call state, the phone is idle and not in use. If the called party is busy or unavailable, the user can select the CallBack softkey to request a call back when the called party becomes available.
E. Off Hook: In this call state, the phone is in use and the user is on a call. If the called party is busy or unavailable, the user can select the CallBack softkey to request a call back when the called party becomes available.
The other SCCP call states mentioned in the question, Remote In Use, Connected Transfer, Ring In, and Connected Conference, do not support the CallBack softkey.
Remote In Use: In this call state, the phone is not in use, but the remote party is on a call.
Connected Transfer: In this call state, the phone is transferring the call to another phone.
Ring In: In this call state, the phone is ringing to indicate an incoming call.
Connected Conference: In this call state, the phone is in a conference call with multiple parties.
Therefore, the correct answers to the question are A. On Hook and E. Off Hook.
