Silent Solution
The Silent Solution system helps filter out accidental or hoax 999 calls from those who need genuine police assistance. If you are calling from a mobile phone and speaking or making an immediate sound would put you in danger and you need immediate help, call 999 and stay on the line, then press 55 when prompted and the call will be transferred to the police who will know its an emergency call. Silent Solution does not apply to calls from a landline as it is less likely to call 999 by accident. If an emergency call is made and no-one speaks and only background noise is heard you will be connected to a police call handler
