Administrators Guide for SIP-T2_Series_T4_Series IP Phones
284
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:
Alert-Info: 127.0.0.1/Bellcore-drN (or Alert-Info: Bellcore-drN)
Alert-Info: ringtone-N (or Alert-Info: MyMelodyN)
Alert-Info: <URL>
Alert-Info: info=info text;x-line-id=0
When the Alter-Info header contains the keyword Bellcore-drN, the IP phone will
play the Bellcore-drN (N=1, 2, 3, 4 or 5) ring tone if the parameter
features.alert_info_tone is set to 1, or play the corresponding local ring tone
(RingN.wav) in about ten seconds if the parameter features.alert_info_tone is set
to 0.
Example:
Alert-Info: http://127.0.0.1/Bellcore-dr1
The following table identifies the different Bellcore ring tone patterns and
cadences (These ring tones are designed for the BroadWorks server).

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