Anyone familliar with NCT or Network Call Redirect?

[Phonetek]

This may be the wrong forum to post this in, but here goes...

We are trying to implement MCI's NCT (Network Call Transfer) feature on our trunk group. The switch on both coasts is an Avaya G3r Version 8. The way that it works is this...

A customer calls into the 866 number, and hits the vector. We are using BSR between 2 different service centers, and the switch looks for a better EWT for the customer. At that point the call is sent to the center with the best EWT. The switch sends MCI the request for NCT, and MCI takes the call up in the cloud, and transfers it to the other center. When the transfer is complete, the originating trunks are dropped. Those trunks being the incoming call from the customer, and the BSR call to the other service center. Currently when a call is sent via BSR, there are 3 trunks tied up, and with NCT there will only be one.

Here is how it's setup in the switch...

The T1's have to be converted to NFAS because the incoming, and outgoing trunks have to utilize the same D channel. The trunk group needs the following changes...

2 way direction
Supplementary Service Protocol set to g
Disconnect Supervision In and Out both set to yes
Network Call Redirection set to ANSI-Transfer

Next the Best service Routing needs to have the following...

The 9 is removed from the Interflow VDN number.
The Net Redirect is set to yes.

That's pretty much all the translation changes. Now here's the problem...

I have a switch in Norfolk, VA. and a switch in San Diego, CA. Both switches are identical release, and have identical programming. NCT works from Norfolk to SD, but not the other way around. The call will transfer from SD, but the original trunks will not drop like they do from Norfolk.

The following text is from an ISDN Protocol Analyzer. The first shows the Norfolk call record, and the second shows the SD call record. The text in red is the request from the PBX to MCI to invoke NCT. The first FACILITY request being the PBX requesting, and the second is MCI acknowledging the request.

As you can see in the SD call record, there is no FACILITY request from the PBX, ,and subsequently there is no acknowledgment from MCI.

So the million dollar question would be WHY?? What switch translation would control that request that is sent to MCI?
