Hi all, Looking to see if someone can provide a sample configuration for Brazil for spandsp.conf.xml Im interested in SIT, REORDER and BUSY or guidance in configuring this file. Here are the Brazil tones: http://www.itu.int/pub/T-SP-OB.781-2003 Frequency in HZ value is understandable, seems to be min and max are tone duration. Where can I find these reference? This is the US sample: <descriptor name="1"> <tone name="CED_TONE"> <element freq1="2100" freq2="0" min="700" max="0"/> </tone> <tone name="SIT"> <element freq1="950" freq2="0" min="256" max="400"/> <element freq1="1400" freq2="0" min="256" max="400"/> <element freq1="1800" freq2="0" min="256" max="400"/> </tone> <tone name="RING_TONE" description="North America ring"> <element freq1="440" freq2="480" min="1200" max="0"/> </tone> <tone name="REORDER_TONE"> <element freq1="480" freq2="620" min="224" max="316"/> <element freq1="0" freq2="0" min="168" max="352"/> <element freq1="480" freq2="620" min="224" max="316"/> </tone> <tone name="BUSY_TONE"> <element freq1="480" freq2="620" min="464" max="536"/> <element freq1="0" freq2="0" min="464" max="572"/> <element freq1="480" freq2="620" min="464" max="536"/> </tone> </descriptor> Thank you
