Declining call forwards it to random number

[Theresa Spencer]

Please help me. I forgot to turn off my phone in the office the other day so when it rang I swiped the decline button. A friend later told me I had no voice mail message. When I investigated I did have a VM greeting so I called my cell from another phone. When my cell rang I swiped decline. The desk phone I was using continued to ring "my phone". After about 6 rings, one of my client's answered the phone calling me by name because my desk phone number had appeared on her caller ID! Really random right?! When I got home I explained it to my husband who thought I was crazy. He called my cell from our home phone and then swiped decline. Our home phone continued to ring "my phone" again for a few rings and my husband hung up. About an hour later, my client calls me back to see who had called her from my home phone number! This is a huge problem! I can't find anywhere on the droid to change settings for the decline button so I am at a loss for what to do.

My phone is an original Droid with all the updates that Verizon will officially allow.

Thanks
