If the tone formats of 13 countries are all not suitable for the client’s request, VOIP
GATEWAY32 allows the user to define the tone according to the standardized format. VOIP
GATEWAY32 support the tone of 3 different melodies, and the format should be:
(C1LowFreq@C1LowFrC1HighFreq@C1HighFreqLevel,
C1TOn/C1TOff);C2LowFreq@C2LowFrC2HighFreq@C2HighFreqLevel,C2TOn/C2
TOff) ;(C3LowFreq@C3LowFrC3HighFreq@C3HighFreqLevel,C3TOn/C3TOff)

Tips
for continuous signal, Ton is time length, TOff is 0
If only one segment melody, all parameters of C2
、
C3 are set as 0.
For example: user can accord the following format to set the tones of Oman:
Dial Tone: 425Hz
，
Continuous:
(425@-15+0@0, 1000/0);(0@0+0@0,0/0);(0@0+0@0,0/0)
Ring Back Tone: 425Hz
，
0.4 on 0.2 off 0.4 on 2.0 off
：
(425@-15+0@0,400/200);(425@-15+0@0,400/2000);(0@0+0@0,0/0)
Busy Tone: 425Hz
，
0.5 on 0.5 off
：
(425@-15+0@0,500/500);(0@0+0@0,0/0);(0@0+0@0,0/0)
Unobtainable Tone: 425Hz
，
0.2 on 0.3 off
：
(425@-15+0@0,200/300);(0@0+0@0,0/0);(0@0+0@0,0/0)
