The situation here in the UK is that the folks who interconnect to
the PSTN have to validate that you own/control the number you
are sending via IAX or SIP. We had a problem where an internal id was  
not
getting overwritten with a valid PSTN number, one of our suppliers
set a default caller-id and another rejected the calls.

The process is annoying, but it works fine, you have to either
use callerids of DIDs you have bought from the same ITSP
or fax them a telco bill indicating your rights to that number.
