Distinctive Ring Tones

Distinctive ring tones allows certain 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 them to the
appropriate ring tone.
If the caller has existed in the local directory, the ring tone assigned to the caller should be preferentially
played.
Alert-Info headers in the following formats can be configured:
• Alert-Info: 127.0.0.1/Bellcore-drN
• Alert-Info: ringtone-N (or Alert-Info: MyMelodyN)
• Alert-Info: <URL>
• Alert-Info: info=info text;x-line-id=0
Refer following details about each header format:
• If the Alter-Info header contains the keyword "Bellcore-drN", and the parameter "features.alert_info_tone"
is set to 1, the IP phone will play the Bellcore-drN (N=1, 2, 3, 4 or 5) ring tone. Otherwise, the IP phone will
play the pre-configured local ring tone in about ten seconds.
Example:
Alert-Info: http://127.0.0.1/Bellcore-dr1
