Band call (4)
I believe the answer is:
ring
I believe this is a double definition.
'band' is the first definition.
('ring' can be a synonym of 'band')
'call' is the second definition.
(I've seen this before)
(Other definitions for ring that I've seen before include "Chime" , "Buzz" , "Toll" , "resonant sound" , "Circle that's square for boxers" .)
