Unity Call Transfer with announce from IPCC

Question

I'm trying to setup a script in IPCC for Meetme users to call into, enter in a PIN number, and be sent to the correct Meetme conference. I've got all of that working just peachy. I was hoping to also be able to use Unity's call transfer with announce functionality using a call handler. Unfortunately through testing and also verified in documentation, the call transfer functionality is ignored for forwarded calls (calls not handled by the unity auto attendant or directory handler).
Can someone enlighten me on a workaround for this? Basically I want the caller to come into IPCC, enter their PIN, IPCC shoot the caller to a Unity call handler which prompts for the user's name, then Unity announce that person's name to the conference and then finalize the call transfer to the Meetme conference.
I've tried all sorts of combinations using CTI route points in call manager, modifying direct and forwarding route patterns in Unity etc. No dice so far to get the call announce working. Many thanks in advance!

I appreciate all the responses. I was able to get this to work, my dunce hat was on and my Unity forwarding rule was sending to the greeting of the Call Handler rather than the Attempt Transfer.
The powers that be at my company wanted to assign a different MeetMe number to each department in order to reduce the risk of multiple people trying to use the same conference line at the same time. I did not like the fact of having to setup 20 cti route points in CallManager, and then 20 call forwarders inside of Unity that then sent to 20 separate call handlers. I found a way to bypass the cti route points and call forwarders by having IPCC send the call directly to Unity.
The trick to bypassing CallManager CTI route points that simply forward to Unity, and setting up call forwarders in Unity is this:
1) In IPCC, use a consultive transfer instead of a call redirect. This allows you to first dial the main voicemail number and then dial the specific voicemail box once you are in Unity.
2) On your call handler in Unity, simply specify the extension number of the call handler (I used the same number as the MeetMe line), and also set the forwarding number.
So I've been able to change the process from Caller->IPCC Script->Callmanager CTI RP->Unity forwarder->Unity call handler->MeetMe to simply Caller->IPCC Script->Unity call handler->MeetMe
As for my IPCC script, I used arrays to handle my plethora of conference lines, it greatly cut down on the size of my script.
