Number calls for about 10 minutes, and then beeps with dial tones.  If you return the call, you hear the same dial tone beeps (Very Annoying)

They called at 5:25 A.M., waking me out of a sound sleep and scaring me to death.  I thought it was the nursing home calling about my 90 year old mother.  When I called the number back, got a recording saying "Person at extension such and such is not available".

Call at 5:32 am (PST), no one on the line. Called a second time, no on there. We called back and get a generic "no one available" message. Freaked out my wife, who never got back to sleep.
