I have a call Pilot 150 version 3.1. It's off a MICS version 7.1. It is on AA all the time. I am getting random complaints of the AA dialing incorrect extensions. I find no pattern to this. Having read thru many previous threads I checked to make sure I have the 8 volt 2 wire power cord. I find none of the receiving phones to have buttons programmed to receive other extensions. No phones have lines on them, every phone is dial 9 off intercom. This system was fine, then the customer moved. I shut the system down, moved it and powered it back up. It is on a UPS. This problem seems to have appeared after the move. The system doesn't have enough spare ports to switch the CP extensions to other ports.
