Reply To: Cisco ATA 186


I’ve been using a Cisco ATA 186 quite successfully however I have a problem which I cannot make head or tail of. Sometimes one of the phones attached to the ATA 186 will not permit calls to get through to their destination and a busy tone is heard. The problem gets worse sometimes and will not let calls get through from both phones, the only solution so far that I’ve come up with is to remove the power supply for a few seconds and reattach it and then it works again. However the problem is becoming more persistent now and this unplugging and replugging in necessary after almost every call. Has nayone experienced this same problem ?
Does anyone have any solutions please?
