As I understand it, the police are told which “dispatcher “ is on duty. This dispatcher is a WEFAS member. Any responding member calls that person and tells them they are going to take the call. The dispatcher will then notify the police that they either have a crew or not. The WEFAS dispatcher will also call for mutual aid if necessary.
This method may change as W Caldwell transitions to NJICS later this year, and WEFAS acquires new portables for their members.
