I expect that people will attest spam. But we're allowed to block carriers by 
spid if we want if we start getting garbage. The effective telecom death 
penalty that'd create (along with the liability) will be an interesting 
enforcement mechanism.

My faith in STIR/SHAKEN has all but collapsed. I think we're just going to end 
up in a situation where even the SPAM is attested. At least having a breadcrumb 
to follow might help.

Given the current state of SS. I won't hold my breath.

Stir will only help if carriers actually pass or allow tokens.  Still waiting 
on several tier 1 carriers to take them.

Hopefully Stir/Shaken will make this a moot point. Calvin, are you saying that 
a 608 is the recommended response for a call that is being rejected due to S/S 
attestation or CVT reasons?

Today we received a notice from one of our underlying carriers that included 
the following statement:

* If a customer spoofs an ANI that they do not own, the clec's can forward to 
call to a voiceless Voicemail which appears to be FAS.

Is there any legal device that actually supports this practice? I'm looking for 
a specific statute, FCC rule, precedent in a judicial ruling, or the like.

The FCC has ruled that the SIP 608 response code is to be used for signaling 
when a call is rejected. I doubt the FCC or FTC has ruled that terminating 
carriers are permitted to cause loss of trust and revenue between upstream 
intermediate and originating carriers.
