Query: Didn't work

We bought a wall phone for our new home, and bought this long cord to use with it. The first time I tried to answer the phone with the new cord on it, the person on the other end could not hear me, but I could hear them fine. I thought it was a fluke, but it happened several times. I made sure the cord was plugged in well, but that still didn't work. So, I put the cord back on that came with the phone, and it worked fine. I didn't save the receipt, so I'll just throw the cord away. Very disappointed.
