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 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)
If the caller already exists in the local directory, the ring tone assigned to the caller should be
preferentially played.
