If I do *#61# query I get that forwarding will engage after 20 seconds when unsanswered. I want to increase this to 30 seconds. I have tried **61*+447870020555**30# and **61*+447870020555*11*30#, where *11* is voice calls and 30 is the delay before forward in seconds. Neither codes are accepted though they do work on EE, Virgin and 3. Can you please advise?
