I believe the answer is:

skype

(Other definitions for skype that I've seen before include "Online phone service" , "Telephone over the internet" , "program" , "Computer-based telephone software" , "Have a spoken conversation via the internet" .)

I've seen this clue in The Times and The Sunday Times.
