Wireless 9-1-1 calls are currently answered by the California Highway Patrol Center located in Vallejo, however some wireless 9-1-1 calls will be answered by the municipal law enforcement agencies above in the near future.

If the caller is requesting medical assistance or reporting a fire or hazard, the call is immediately transferred over a dedicated telephone 9-1-1 trunk to the Fire Communications Center. CCRFCC dispatchers then answer the call and interrogate the caller. Along with the transferred call, the dispatcher receives on a display, the telephone number and address of the caller. CCRFCC dispatchers enter information given by the caller into a Computer Aided Dispatch system. The CAD system:

Verifies the validity of the address range
Provides nearest cross streets
Provides map page and coordinates
Determines proper units to dispatch based on incident type
Provides information on Premise when available
Activates the alerting system in the Fire Station and sends a printout to the station printer
If the call is for medical assistance, the CCRFCC dispatcher will ask the caller to stay on the line and will provide "Pre-Arrival" and "Post-Dispatch" instructions.
