[VoiceOps] Cisco SBC - feedback ?

I asked this same question over on Cisco-NSP the other day and got zero responses; I am in the same boat you are, Ben, and am very interested in anybody's opinions/history with this hardware. I recently came across Cisco?s offering for a SBC -> The ?ACE20-SBC-K9?

http://www.cisco.com/en/US/docs/routers/7600/install_config/sbc_config_guide... I was Curious who out there uses this and what their thoughts on the product was or any feedback for that matter on it. Up until recently we were heading down the Acme Packet path, however most of our Current infrastructure is Cisco, so it kinda of makes sense to take a serious look at this.
