Whether the ATA or VT's server provides the CID info, I don't see how they would know they don't own the number anymore, so spoofing it at that level is not unbelievable. Or am I misunderstanding?

I suppose the short answer would be to ask the person or better yet the persons being called, what they see on their screen.
Typically, the outbound call will dip into one of the national CID tanks and send that on to the receiving end...if the number resides in the tank.
When I get a chance, I will make a few calls to try for an answer on this.
When I had a ViaTalk trunk set up on my Asterisk/Trixbox server, I found that VT's system would override the CID setting I had indicated in the FreePBX trunk setup. I'm fairly certain that calls from your VT line will send the VT-assigned number for CID purposes. One thing that seemed to work for CallVantage (but does come at a price): Consider getting a virtual number for your VT line after you port your primary number away. That way, outbound numbers would still show your (now-ported-away) number, but anyone dialing the virtual number would still ring through to your VT line.
