Query: The headset didn't work!

I did everything the instructions said, including installing the 4 AA batteries before attempting to use.. But for some reason, when I plugged the included headset into its port, the speakerphone shut off like it should have, but there was no sound in the headset speaker. When I picked up a different phone, I could hear what I was saying into the headset, but no sound was coming out of it.Also, when using the speakerphone, I noticed that the sound had some "quiet intervals"; the sound would stop for a second or two. This became very annoying, so I just gave up with this phone altogether. I plan on returning it.
