The phone company scans lines to see if they are in service. This can
produce one or more rings on a phone. If answered, you will usually get
"dead" line, or an odd tone. Another possibility is some sort of automated
phone sales or political call. If there is no answer within a few rings,
either will usually disconnect. One thing to remember is that the caller may
hear more rings than the called. This is usually one, but may be two rings
or more difference. Cell phones in particular seem to be subject to
different rings heard between callers and called. (Even cell phone to cell
phone when both use the same provider.)
