Distinctive ring tones allows particular incoming calls to trigger IP phones to play
distinctive ring tones. The IP phone inspects the INVITE request for an "Alert-Info" header
when receiving an incoming call. If the INVITE request contains an "Alert-Info" header,
the IP phone strips out the URL and keyword parameter and maps it to the appropriate
ring tone.
