Good (sobering) points Tony.

I guess that, at a minimum, I need to no longer allow my users the option of 
blocking caller-I'd, since I know and have tested that 911 address lookup works 
when I don't tell sipx to block.

As far as an SBC goes, I am not really sure where to look.  Is flexible 
handling of trust and asserted identity a strength of any SBC anyone can point 
me to?

Thanks,
Jeff
