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 or keyword parameter and maps it to the appropriate ring
tone.
Note
Alert-Info headers in the following four formats:
1) Alert-Info: Bellcore-drN
2) Alert-Info: ringtone-N (or Alert-Info: MyMelodyN)
3) Alert-Info: <URL>
4) Alert-Info: info=info text;x-line-id=0
1) Alert-Info: Bellcore-drN
When the Alter-Info header contains the keyword ―Bellcore-drN‖, the IP phone will play
the desired ring tone.
The following table identifies the corresponding ring tone:
Value of N
Ring Tone
(features.alert_info_tone = 1)
Ring Tone
(features.alert_info_tone = 0)
1 Bellcore-dr1 Ring1.wav
2 Bellcore-dr2 Ring2.wav
3 Bellcore-dr3 Ring3.wav
4 Bellcore-dr4 Ring4.wav
5 Bellcore-dr5 Ring5.wav
6 Ring6.wav
7 Ring7.wav
8 Ring8.wav
If the caller already exists in the local directory, the ring tone assigned to the caller
should be preferentially played.
