[VoiceOps] Phone Spoofing - Anything we can do?

[John S. Robinson]

In a SIP environment many UA's have a feature "only allow INVITES from 
SIP registrar" or words to that effect.  Another possibility might be to 
challenge incoming INVITEs (and other SIP methods) if the host switch 
and CPE supports challenge.   (Metaswitch for example is actually quite 
aggressive with use of challenge responses on most transactions.)

Those SIP techniques along with good IP access control or NAT can 
substantially reduce SPIT (SPam Internet Telephony.)   Is there a 
Federal "Truth in Caller ID Act?"  If yes, it is probably only 
enforceable on Interstate calls, and then you need to find someone who 
has the competence, standing and urgency to enforce it.

I am not a lawyer, but I know that law can vary from State to State.  
Illinois had a "don't lie about caller ID" statute before our 
legislature, but it got voted down.
