Silent Solutions is a system for victims of domestic abuse who might be afraid of further danger and escalation of harm if they are overheard when calling 999 in an emergency.

When somebody calls 999, an operator will ask which emergency service is required. If the caller is unable to audibly signal to the operator, the call will be forwarded to an operating system.

If 55 is pressed by the caller, the system will detect this. The operator will then transfer the call to the relevant police force as an emergency.

National helplines, email, text and live chat support services, and local specialist services, are currently open for business as usual, although their delivery is likely to have to adapt over the coming weeks.
