Appendix G. User Defined and Fixed Ring Types
The IP8820, IP8830 and IP8840 support 14 ring tones that are assigned to the phone (default
ring type), lines and Phone Book entries. Of these, four (4) are stored PCM tones and an
additional five (5) tones are stored in memory as *.wav files. Note Ring type 1 is used in
conjunction with the cadences to establish the audible ring for a call.
The remaining five (5) Ring Types can be downloaded using an RTTTL text formatted file. An
RTTTL file can be downloaded from a number of Web sites including www.csoft.co.uk/ringtones
or constructed using RTTTL to generate a text file, which is downloaded to the phone. With
RTTTL, a melody is constructed by building musical notes. Each melody is named, and multiple
musical notes and commands, which consist of duration, scale and beat, are defined. The IP
Phone plays the melody in a loop, replaying the melody until the call is answered or abandoned.
The text representation of a tone is
<name> <sep> [<default>] <sep> <note-command> delimiter
<name>: = ten (10) character name, use Ring Type names, 201, 202, 203, 204, 205
<sep>: = “,” comma
<defaults>: = “d= l o= l b= “ where:
d = default duration:
“1” l -Full note
“2” l - ½ note
“4” l - ¼ note
“8” l -

o = default scale:

“6” l – note A is 880 Hz
“7” l – note A is 1.76 KHz
“8” l – note A is 3.52 KHz
b = default beats per minute,
If not specified, defaults are:
d = 4, ¼ note
o = 6, note A = 880Hz
b = 63 beats per minute
<note-command>: = [<duration>] <note> [<scale>] [<special duration>] <delimiter>
<duration> = same as for default
<note> = musical note
“P” l for pause
