Jitter Buffer
Rainbow 1 is able to buffer incoming voice packets to minimize out-of-order packet arrival. This
process is known as jitter buffer.
1.
Type: Choose type of jitter buffer. When choose Fixed, the size of jitter buffer is fixed. When
choose Adaptive, the size of jitter buffer is the sum of Minimum Delay and the size of RTP
packets.
2.
Min Delay: The minimum delay of the jitter buffer.
3.
Max Delay: The maximum delay of the jitter buffer.
4.
Normal Delay: This is used to set fixed jitter buffer which should be between Min Delay and
Max Delay.
4.5.4 Ring
Administer can upload 2 user define ring. The ring file should be wav (8k, 8bit, u-law) and no larger
than 200 KBytes.
4.5.6 Tone
Set the ToneScript for each tone.
For example, MWI Dial Tone:
350@-19,440@-19;2(.1/,1/1=2);10(*/0/1+2)
Frequency1, Frequency2 ;Cadence Section1;Cadence Section2
350@-19
: Frequency1 is 350HZ at -19dBm
440@-19
: Frequency2 is 440HZ at -19dBm
2(.1/,1/1=2)
: Cadence Section length is 2s, 0.1s on, 0.1s off, with frequencies 1 and 2
10(*/0/1+2)
: Cadence Section length is 10s, always on(* means always, 0 means never), with
frequencies 1 and 2.
