[cisco-voip] Conference Call Oddity? mysterious resources

OK, so I'm testing out my new conference resources on two 3945s. I've set up 4 profiles, two which handle 4 x 16 participants and 2 x 16 participants. I set up a new media resource group with these resources and assigned it to a new list and assigned this list to 12 new phones. 

I tested 12 x 9 participant conference calls using voice mail ports and a call handler with a repeating greeting. Everything worked as expected. Saw appropriate IP addresses on the "show voip rtp connections" output on the two routers. 

So this is where it gets funky. I wanted to see what a failed conference call would look like. I configured another phone with the same resource group list and initiated a conference call. It WORKED! 

I could not find the call from this phone on either of the two routers -or- the old 6608 blades. 

It's a 7940, so I can't imagine it was using an internal bridge. I thought that was only for a few calls. 

What the heck?
