This number keeps calling my phone with no message.  When I call back I just get a busy signal.  When I try to send a text message (stop calling this number), my phone just keeps trying to send the message, but it won't go through.

This number - 206.441.5927 - starts calling a clinic emergency back phone line at approximately 5PM each evening.  When I answer these calls, its the sound of a fax machine trying to send data.  If I call the number back, it's always busy.  Calls to the phone company to have this number blocked have been unsuccessful - they've told us we need to pay $4.95/month to block the number even though they are the crank caller and it's interrupting emergency medical calls!  If anyone knows who owns the line, please let me know.
