Given a call which is received via SIP at a Cisco router IOS Version 12.4(15)XZ2
and is thereafter directed to an embedded AIM-CUE module which triggers a VXML
script, is is possible to retrieve the SIP "From" header of the call within the VXML
script?
The utility of retrieving the SIP "From" header is
that it (in our case and typically in others) contains the presentation-format calling party information (that is, the
name and/or physical address of the caller). A
variety of documented methods (such as "session.telephone.com.cisco.handoff.proto_headers['From']" and
"session.com.cisco.proto_headers['From']) simply do not work and instead cause VXML
script execution to terminate and a Cisco-supplied "We're having technical
difficulties" message to be played to a caller.
If it isn't possible to retrieve the raw SIP "From" header via a called VXML document, is there any other way to obtain the same information fragment? Is any alternate method documented somewhere?

The relevant part of the AIM-CUE trace appears below. I notice the portion which reads " EXCEPTION:com.cisco.app.ApplicationException: Voice Browser exit with error; nested exception is: com.cisco.voicebrowser.VBEvent: error.semantic: Error in eval(): var hdrf=(session.com.cisco.proto_headers['From']);; nested exception is:
undefined: The undefined value has no properties."
Again, the IOS version is 12.4(15)XZ2 and the CUE version is 7.1.1.

If you think is IOS Voice Gateway VXML related you need to open SR with Developer Services contract
If it just a IOS issue you can just open a normal TAC SR.
In the mean while I suggest you collect "deb voip app" and "deb voip ccapi inout" post here, someone will take a look. But as you know this is best effort support.
Thanks
