asterisk users - Feb 2007 - Using Asterisk/callerid with "pay as you go" VOIP providers

I am curious how others handle "call out" VOIP and callerid. I have
found
numerous providers that are cheap and seem to have good voice quality but
offer no provisions for callerid.  I find it almost useless to use call
out when the receiving party gets some bogus callerid number that has no
relation to my call.

I understand the big thing is spoofing callerid but are there any
companies that offer a means of qualifying callerid so it works right?

Like it or not callerid is used heavily and without a proper return ID
many callee's don't answer and if they tried to return the call they get
no where. Seems like a big problem to me.

Very aggrevating.
