Phoned or visited (6)
I believe the answer is:
called
I believe this clue is a double definition.
'phoned' is the first definition.
('call' can be a synonym of 'phone')
'visited' is the second definition.
('call' can be a synonym of 'visit')
(Other definitions for called that I've seen before include "Assigned a name to" , "Named" , "Phoned or visited" , "Having a specified name" , "Summoned or phoned" .)
