In a full-on VoIP to VoIP setup, it's up to the sending station to set correct and meaningful CLI information. (you have both a number and a name to send/manipulate) The receiving station either has to trust it, or ignore it. The best you have to authenticate/validate on then is the IP address of the sending station, and if that's your brother on holiday on a round the world trip, it's going to be hard... Things are usually different when a sending station connects to an ITSP to place calls to the PSTN - in that case the ITSP can force outgoing caller ID, regardless of what the sending station sets.

Sure... if you trusted the caller ID. Spammers already forge sending email addresses - no reason why they won't try to do the same with VoIP CIDs.. > I suspect the TPS leglislation would apply to anyone working from or > paid from within this country, IANAL but I think a judge might say "and > this is a technology for making telephone calls?" The few judges (magistrates) I know are fully VoIP aware, but I know what you mean...
