Alert-Info headers in the following four formats:
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
 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 preconfigured local ring
tone in about ten seconds.
Example:
Alert-Info: http://127.0.0.1/Bellcore-dr1
The following table identifies the different Bellcore ring tone patterns and
