Note

If the Alter-Info header contains the keyword “ringtone-N” or “MyMolodyN”, the IP
phone will play the corresponding local ring tone (RingN.wav). Otherwise, the IP
phone will play the preconfigured local ring tone in about ten seconds.
Example:
Alert-Info: ringtone-2
Alert-Info: MyMelody2
The following table identifies different ring tones.
Value of N Ring Tone
1 Ring1.wav
2 Ring2.wav
3 Ring3.wav
4 Ring4.wav
5 Ring5.wav
N<1 or N>5 Ring1.wav

If the Alert-Info header contains a remote URL, and the parameter
“account.X.alert_info_url_enable” is set to 1 (the item called “Distinctive Ring Tones”
on the web user interface is Enabled), the IP phone will try to download the WAV
ring tone file from the URL and then play the remote ring tone. Otherwise, the IP
phone will play the preconfigured local ring tone in about ten seconds.
Example:
Alert-Info: http://192.168.0.12:8080/Custom.wav

If the Alert-Info header contains an info text, the IP phone will map the text with the
internal ringer text preconfigured, and then play the ring tone associated with the
internal ringer text. Otherwise, the IP phone will play the preconfigured local ring
tone in about ten seconds.
“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.
