I had this back in 2006. This digital answering machine has its good and bad points. On the good side, it is compact and light, with some nice features like remote access (you can check your messages if you are away from home), message guard (if you experience power outage, your messages will not be lost), and number announce (if you have caller ID, the machine will speak out the incoming number after a couple of rings). This answering machine has good memory, too, it will store up to 99 messages / 40 minutes of time.
However, there are drawbacks as well. Sound quality is just bad. Remember those now extinct tape-recording answering machines where you had to rewind the tape all the time? Well, those offered far better sound. This one is muffled and unclear. Another thing that really, really irritated me and my callers is that the machine would only give the caller a very short time to leave a message - something like 6-7 seconds, and if they took a bit longer figuring out what to say in their message, it would disconnect the call. This was very annoying.
You'd think an AT&T brand would be reliable. We bought one the cheap drugstore brand ones and it gives us similar issues, so now we've just decided to let Verizon do this auto-messaging system where we call up a number and hear messages left for us instead of rely on a machine.
