Review on 📞 AT&T 964 Corded Expandable 4-Line Intercom Speakerphone: Graphite with Digital Answering System by Troy Williams

In other words, many declared functions, many of which are not needed, contradict each other and are poorly documented. We also found that this unit (despite not being a 944 slave unit) was prone to (static) radio interference, so we had to move it to another room. How much is your time worth? Expect at least 5 hours to get this turkey up to the minimum working level and never get it to work fully. Since RFI are generated by an autoresponder, you should consider purchasing a separate autoresponder. The first one we bought from AT&T turned out to be defective. Instead, we chose the Panasonic KX-TM100B [ASIN: B00000J53X]. You'll save yourself a lot of hassle if you buy it instead. Another reviewer recommends the Voice Logic Voice Pro 412 system. I have no experience with it, but I don't see how it can be that bad. If you are buying this or have already bought it, be sure to download and save the instruction manual. Otherwise, you'll have a hard time finding a manual once Amazon has stopped selling it. This is obviously good advice for any electronic product.
