I believe the answer is:
call
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">contact by phone</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for call that I've seen before include "Ireland's ..., rugby anthem" , "Visit; cry out" , "Pay a visit" , "Be in control" , "Summon; shout" .)
