DTMF capture

[Guest cosmin111]

Is possible to intercept DTMF tone sent by another phone?

I modified CEDIALER SDK sample by inserting lineMonitorDigits in callback function , when phone is connected (LINECALLSTATE_CONNECTED) , but function allways return LINEERR_OPERATIONUNAVAIL error code.

Also I modified media mode from LINEMEDIAMODE_DATAMODEM to LINEMEDIAMODE_INTERACTIVEVOICE but i got same result.

This error occured both on emulator and on my smartphone SPV C500.

Thanks for any ideea .
