Exam 300-810 topic 1 question 87 discussion

Sorry, C is correct, Release to Switch—Unity Connection puts the caller on hold, dials the extension, and releases the call to the phone system. When the line is busy or is not answered, the phone system—not Unity Connection—forwards the call to the user or handler greeting. This transfer type allows Unity Connection to process incoming calls more quickly. Use Release to Switch only when call forwarding is enabled on the phone system

I will go for B, Select the number of times the extension rings before Unity Connection plays the user or handler greeting. Set this value to at least three to give users a chance to answer. Avoid setting to more than four, especially if the call may be transferred to another extension, where the caller might have to wait for another set of rings. This value should be at least two rings fewer than the phone system setting for forwarding calls.
