Is this an 800 number?  If so, and maybe if your telco is very nice, you 
can get ANI.  Toll free lines get ANI for billing purposes but it is 
much more useful than just billing.  Sometimes you just have to request 
it.  ANI cannot be blocked like callerID.  If the spammers are 
sophisticated enough, they can still get around the ANI but I doubt they 
are.

BTW OT from another thread, I upgraded IAXmodem and used the example 
Hylafax modem config files instead of using Hylafax's addmodem and 
things seem to be much better.  Keeping my fingers crossed and will load 
first thing Monday.

Thanks,
