DTMF detection

7 years 2 months ago #8336 by amapro
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.
