Hi All, There exists a library libteletone. I know that it has functionality to detect and generate DTMF tones, but I didn't get any help as to how can I test it with my FreeSwitch configuration, as no document is available on http://wiki.freeswitch.org/wiki Is there anybody who used detection and generation of DTMF tones using libteletone library in FreeSwitch and can help me to use it? Thanks in advance. Dinesh
