2) Alert-Info: ringtone-N (or Alert-Info: MyMelodyN)
When the Alter-Info header contains the keyword “ringtone-N” or “MyMolodyN”, the IP phone
will play the corresponding local ring tone (RingN.wav), or play the first local ring tone
(Ring1.wav) in about 10 seconds if “N” is greater than 10 or less than 1.

If the user is waiting for a call, “Bellcore-dr5” is a ring splash tone that reminds the user that the
DND or Always Call Forward feature is enabled on the server side.
