We recently added a new line card to a Nortel system we manage. One of the new numbers we added will ring 4 times on the phone it is suppose to, but then gets forwarded to the intercom button of a completely differnt phone. When you answer it, it says "Transfer from 15." The CO line of the number is 15. The other 2 numbers we added to this card works fine, so we are thinking it's some long ago put in place forward we can't find. We checked the capableities of the the set the line is set on but there is no call forward no answer put in place. I don't think this is the problem though as other numbers ring there and don't get forwarded. To solve this problem for now, we are moving the number to CO 16 but we would like to solve the problem if the cusomter ever wants to add another line.
