I hope you're right. But also remember that the OP will also do this if they know the right number to use. I don't suppose you might be able to try *69 where you live. If it's an unlisted number, won't do you any good, but might be worth a try.
If it IS you're daughter, just hearing your voice may be her reason for hanging up after calling. Not ready just yet to reach out to you, but the comfort from hearing your voice fills a void she no doubt feels.
I just have to warn you that if she passed that number along to your XH (coerced to do), it could very well be TrickBoy or his slimey sidekick. Keep a journal of these calls if you can. They can always be traced if necessary down the road.
And remember, don't react to these calls. No reaction is the best reaction.
