The Distinctive Ring Tones feature allows specific incoming calls to trigger the IP phone
to play the distinctive ring tones. A SIP server can insert the ―Alert-Info‖ header into the
INVITE request, the ―Alert-Info‖ header specifies an alternative ring tone to the IP phone.
When the IP phone receives an incoming call, the IP phone inspects the INVITE request
for an "Alert-Info" header. If the INVITE request contains no "Alert-Info" header, the IP
phone will play the default ring tone configured on the IP phone. If the INVITE request
contains an "Alert-Info" header, the IP phone strips out the URL and keywords. The IP
phone tries to download the ring tone from the URL and play it. If failing to download
the ring tone, the IP phone maps the keywords to the predefined criteria and plays the
distinctive ring tone. The following are two examples of "Alert-Info" headers:
Alert-Info: http://127.0.0.1/Bellcore-dr3
Alert-Info: <http://192.168.0.12:8080/ring.wav>;info=Family;x-line-id=0
 If the URL contains the keywords ―Bellcore-drN‖ or ―MyMelodyN‖, the IP phone will
strips out the index ―N‖ from the keywords ―Bellcore-drN‖ or ―MyMelodyN‖, and
