[cisco-voip] dtmf from cucm to 2821 cube to sip trunk

[Dane Newman]

Hello,

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.

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?

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?

The settings in my cuc 7.x to add the gateway h323 are

h323 cucm gateway configuratration
Signaling Port 1720
media termination point required yes
retry video call as auto yes
wait for far end h.245 terminal capability set yes
