When the Alter-Info header contains the keyword “ringtone-N/ringtone-RingN” or “MyMolodyN/MyMelodyRingN”,
the 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-Ring2.wav
