A phone that is right for artist's studio (7)
I believe the answer is:
atelier
'artist's studio' is the definition.
(I've seen this before)
'a phone that is right' is the wordplay.
'phone' becomes 'tel'.
'that is' becomes 'ie' ('i.e.' can be a synonym of 'that is').
'right' becomes 'r' (common abbreviation).
'a'+'tel'+'ie'+'r'='ATELIER'
'for' is the link.
(Other definitions for atelier that I've seen before include "Artist's studio (French)" , "room for artist" , "Artist's workshop, studio" , "I relate to workshop used by artist" , "Tie earl up in the artist's place" .)
