I cannot determine what is happening to your lines to which I have to leave up to the experts here to assist you with.

I can tell you what I think happened on the "A third time" issue. If her phone is on "Send Calls" and you dial her, she will hear a partial ring before it goes to voice mail. She may have quickly picked it up but the cover path already took you to voice mail. Send calls happens either intentionally when you press a dial feature code such as ours which is *3... or sometimes my system will just toss an extension on send calls all by it's self. Check that persons extension by (status station xxxx) and see if it's on send calls. Then you will need to check in your feature access codes to find out which number/symbol sequence puts a call on send calls and which number/sequence cancels send calls. This may only be one piece to your puzzle but it may help.
