Rings, calls up (6)

Ross

I believe the answer is:

phones

I believe this is a double definition.

'rings' is the first definition.
('phone' can be a synonym of 'ring')

'calls up' is the second definition.
('phone' can be a synonym of 'call up')

(Another definition for phones that I've seen is " 'Calls, rings (6)'".)

I've seen this clue in The Irish Times.
