Yes most of these things have a telemetry mode. The phone I have can do it in either voice (via a stored voice) or by a modem. In either case you need an correct access code. The phone will answer an incomming call by itself if no one answers the call after 5 rings (programmable). If the phone is programmed not to accept customer's incomming calls this value may, of course be one. By the way, the phone cam be programmed to call home if it's coin box is getting full, if no calls have been made for a period of time (indicating a fault) or if the phone is being vanalized (there are some switches inside the box).
