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