When the digital answering system kicks in, can you hear your recorded message over the phone's speaker and then can your hear the caller leaving the message and interrupt to take the call?
Caller ID is from your phone company. Your phone company sends callerID information to your phone no matter what phone you have. It sends it. You just have to have a phone that accepts caller id which this one does. Also call-waiting callerid works too.
Yes you can. Call the number of the phone with the answering machine. When the machine picks up, enter 500 and follow the instructions. I believe this information is in the booklet that came with the phone.
Yes you can! You can choose an access code to use when calling in, then there are options as to listening, repeating and erasing messages. All in the instruction manual. It is easy to do !
