<div>Hello,</div>
<div> </div>
<div>I am having an issue with dtmf working outbound. Inbound dtmf works fine. It took some playing around with it. At first it didnt work till the payload was ajusted. I am now trying to get outbound dtmf working properly. </div>
<div> </div>
<div>On my 2821 I debugged voip rtp session named-events and then made a call to a 1800 number and hit digits. I didn't see any dtmf output on the router nothing showed up in the debug. Does this mean I can safely asume that the problem for right now is not on the ITSP side but on my side since dtmf is not being sent down the sip trunk?</div>
<div> </div>
<div>I have my cuc 7.x configured to talk to my 2821 via h323. The configuration of the cisco 2821 is shown below. Does anyone have any ideas what I can do so dtmf digits process properly outbound?</div>
<div> </div>
<div>The settings in my cuc 7.x to add the gateway h323 are</div>
