TTY 911 Calls

All calltakers at the Cambridge Emergency Communications Center are trained to use a TTY in the event of a 911 silent call. A TTY is much like an instant messenger program in which the caller and dispatcher can communicate using a keyboard. Hearing impaired persons reporting emergencies should dial 911 or (617) 499-9924.

The Massachusetts State 911 Department performs test TTY calls every month.
