Review on 📞 AT&T 1070 4-Line Expandable Corded Phone System: Caller ID/Call Waiting, Speakerphone & Handset - Black/Silver by Angeline Darpino

I have 11 of these phones in various places around the house and in a nearby barn. They work very well and are a very easy and inexpensive way to build an office style phone system. Although the manual states that the total length of the phone line should be less than 300 feet, my system has about 400 feet of wire and works with no problems. my phone company's answering service. The 1040 and 1070 also work very well, they just don't have as many features. I started building my system a few years ago. AT&T has a newer system, but I don't think you can mix different types of phones. I've never had any problems with any of the phones in this series. The phone will function normally even if the backup batteries are exhausted. If you use 9V backup batteries, I recommend using rechargeable ones. Where I live we lose power quite often and phones use a decent amount of power to keep working during power outages. You may not have this problem. Even after prolonged power outages and phones with dead batteries, the system will function normally when power is restored - none of the programmed settings will be lost.
