What's the best way to retrieve the original TFN dialed in a Speech Application? It shows up in the EPM reports, for example, sip:1866870xxxx@uhc.com:5080, as the Destination Number, but we're not seeing it anywhere in the Session variable. We were able to see that it's in the SIP header in the To field, but so far haven't been able to retrieve it.

We did try using a Capture Expression object in the root node, as the description said it can be used to retrieve SIP header information, but were unsure of what to put into the Expression field, we tried putting the location like "hints.sip.to" but either retrieved nothing or the app would crash, I'm unfamiliar with ECMA scripts so wasn't sure exactly how to format one to retrieve SIP information.

thanks!

What do you mean by TFN? Seems we aren't familiar with that acronym.
