Can these systems share the phone line with an answering machine or fax?
Yes. If you have a telephone answering machine attached to your telephone line, the Sensaphone or Freeze Alarm can be instructed to allow you to call into your system without having the answering machine or fax answer the telephone call! Anyone else calling your number will go to the answering machine or fax as normal, but you will bypass the answering machine by a simple calling procedure.
