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" .)

I've seen this clue in The Telegraph and The Guardian.
