Hi Michael,
Do all 3 of your CO lines allow outward calls? You might be able to test if the Panasonic, for whatever reason doesn't think the first call succeeded, and after some sort of timing interval chose to try calling out on another line. This assumes that the Panasonic 'rolls' that way. If it's possible, perhaps you could test with one of your sympathetic callees ,after temporairly disconnecting two of the co lines? This is a stumper, and I cannot think of any NETWORK based reason for a second call to sent to the callee. On the other hand, I suppose anything's possible on the Network side, but I'm at a loss to think of any valid reason. The only other clue to help isolate the cause is if your co lines identify by unique numbers, and the callees see two different numbers when called, suggesting that he Panasonic is seizing the second line and re-calling. If the SAME number appears, and you don't have them Optioned to identify by the same number, then I'd suspect the network. Good hunting!!
Yes - all three lines allow outwards calls - they're normal lines that show up on all stations. But so far only one line, the first one, has shown this problem.
When this happens we don't see any evidence of a new call initiated on another line and besides, the first line is the only one with a caller ID like the one showing up at the receiving party. Their cell phone shows the same caller ID (it's coded for my wife's name) so the called party who is on the cell phone engaged in a call with my wife, see my wife's caller ID as calling them again.
I've never seen the Panasonic initiate it's own calls and I don't believe a switch can initiate a new call on the same line that's being used.
So I'm less motivated to disconnect two COs and remember I can't duplicate the problem locally anyway so I have no effective way of testing this yet. I can't really engage my wife's business clients in testing our network.
Thus I've said elsewhere i really need to get more data and try to find a way to test and duplicate this problem.
