DTMF in BackToBack Call that is Conferenced

Hello All,

I am having an issue detecting when an analyst presses a key to send the DTMF to an outside company's IVR.

My setup is: Analyst clicks a case to call, Lync Client calls my UCMA app, UCMA app creates a conference, then backtoback's the agent to the conference, plays a WMA dialing sound to the conference, sends out an invitation to the phone number from the case clicked, and terminates the WMA player when the invitation state has changed.

When the case is a company that has an IVR, the DTMF does not get passed through the conference.

Thanks!
