<div>Hi all,</div>
<div> </div>
<div>I am trying to get DTMF digits from X-pro, through a grandstream ATA, to a FXS to FXO converter for outgoing PSTN calls. I could hear second dial-tone from the phone line connecting to the converter. However, no PSTN dialing occured after DTMF digits was sent from X-pro. I tried while X-pro, * and ATA were configured with rfc2833 and then inband. However, all failed.
