Auto reconnect after enquiry

[CW]

Scenario:
a. Set A in communication with Set B.
b. Set B press the "Enquir" button and call Set C
c. Set A on-hold. Set B in communication with Set C.
d. Set C on-hook.
e. Ring back at Set B (by Set A which was put on hold just now)

Question:
Is it possible for Set B to reconnect with Set A automatically at "Step e" above without requiring Set B to press anything?
