Yesterday I called a local provider to inquire about an appointment the following week and I let the phone ring 5 times.  It was just after ten pm and I hung up on the 5th ring, my  phone immediately rang.  She was on the phone we spoke for a few minutes and then hung up.  I cannot figure how she was able to call me back.  I called from my work cell phone and even used a calling card.  I know there is a feature you to call back the last call when you use a calling card I did not thing it was possible.

And if she has an 800 number there's NO way to hide your number.

It's more complicated than that, and there are a lot of variables involved that determine whether you're caller ID makes it all the way through the calling card transaction or not.  There's no technical reason why the calling card company can't take your incoming caller ID and re-populate the caller ID field of the outgoing call with the same data.

REMEMBER...  The purpose of a calling card is to simplify the financial transaction between you and the phone company, NOT to create confidentiality.  The fact that MOST calling cards don't pass caller ID MOST of the time is a handy byproduct but is by no means assured.  In fact, it may become more and more common to pass the data along.

If you're interested, take a look at my rather long-winded post on this in a previous thread at the link shown.

I tossed out my MCI card after they revealed that they had changed their policy due to consumer complaint regarding their sheild numbers.  Prior the number had come up UNKNOWN. or OUT OF AREA.

Doesn't mean I don't TEST the ATT card on a regular basis, however, so far, so good.  It passes me through either COLORADO or GEORGIA which is what shows up on the caller ID.

Reumb question about cell phones

Not all cards reveal your number. I vaugely remember something about ne2-phone cards for example, but not sure.
