Note
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.
Examples:
Alert-Info: ringtone-2
Alert-Info: ringtone-2;x-line-id=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.
