Few NA volunteers are needed . There is no security that only trained NA volunteers will answer the phone . Calls can be transferred to an NA volunteer several ways : by an answering service , by call forwarding , by voice mail , by computer routing , or by diverter box . Some services take a message and contact the NA volunteer by phone or pager .
