Three times while dialing out the phone would hang up and say NO SIGNAL---CALL ENDED. I have only been using this for about a month. I live in the major city and I immediately used a plugged in landline phone and the call was completed. Tried this phone again after completing the call and had the same issue so I had to go unplug it and reset it. I didn't have this problem with the other phone system. I am not happy with this one. I previous had a 4 receiver phone and switched up to a 6...... wish I would have kept the 4 receive phone instead of giving it away.
