There are issues for those of us that use multiple upstream carriers for 
call termination, with LCR for example.  If you send your calls out the 
same provider that supplies your inbound DID, your calls should get the 
"A" rating and your callers should have no issues. At present if I send 
calls out a provider that does NOT handle the DID in the caller ID 
field, it gets a "B" rating.  I don't think this will pose a problem for 
the forseeable future - I don't see carriers marking these as "spam",  
they just won't get the ultra-special "secure" mark.

Also good to note the upcoming deadline does NOT mean call blocking, 
just call tagging.  The blocking bit will be up to the end user, though 
I could see phones shipping with default settings that may do so.

Basically we can't do LCR anymore.  Outbound calls are locked to the 
provider that gave us the DID.  I'm not sure that's really a bad thing, 
its less headache than for us to try to become a signing authority.

I think the whole thing is still very fluid.  Didn't even mention call 
forwarding issues.
