I installed the cardOpenVox B200P and I can not put into operation affects the inverterDTMF detection. In the manual is presented: “DTMF detection on allB-channels.”
When you call the function:
val =DAHDI_TONEDETECT_ON | DAHDI_TONEDETECT_MUTE;
int res = ioctl(FILE_DESKRIPTOR, DAHDI_TONEDETECT, & val);
it returns -1.Detection does not work. T1/E1/J1 cards “vpmdtmfsupport”parameter exist, but for the BRI card does not exist.
Pleaseadvice how to enable hardware DTMF detection marks on card OpenVoxBRI.
