Can a Computer Room Guard and an answering machine or fax machine share the same line?
Yes. To have the answering/fax machine answer the phone, program the Computer Room Guard to answer the phone on the 5th ring. To access the Computer Room Guard, call the number and let the phone ring 3 times. Hang up and wait 20 seconds. Call the number again and on the 2nd ring the Computer Room Guard will answer.
