My turn to jump in, just because I've been wrestling with caller id spoofing for my own (totally legit) reasons.
> >>> Does anyone know if CID spoofing is legal ? IANAL, but I think it is. The ability to change the callerid on PRIs is not new. Impersonating someone is not legal, so displaying someone else's telephone number without their permission/expectation can probably get you into trouble. > This is not a good idea for many reasons. Flipping the business model > on its head, you really need to look at what honest purpose this would > serve. The proposed business model in this thread is a type of click-to-call service with caller-id spoofing. For that, I cannot really think of a legit reason for spoofing CID other than practical jokes. As for bill collectors, they either show their number, or block it altogether -- I've had enough call me to know! :-) However, the requirement to 'spoof' the caller-id is quite legitimate. A voicemail service provider doesn't want to display the voicemail access number but rather the customer's number when the customer uses an instant-callback feature. An long-distance provider wants the same feature. And since I'm sure the question is on alot of people's minds: Asterisk can spoof callerid depending on what protocal the outbound call is using. With the IAX providers I've used, I've been able to 'spoof' pretty much anything to any destination, either in the dialplan or in sip.conf for the user. With SIP providers (using Cisco gateways), neither STABLE nor HEAD support Remote-Party-ID for outgoing calls. I recently started working on a patch (still have to do proper 'screen' and 'privacy'), and can 'spoof' the CID on outbound SIP calls also. (If you use SER to proxy outbound calls from your asterisk server to your SIP provider, it may be easier to have the Remote-Party-ID header added there rather than patching chan_sip). No experience with PRI connections (until next week anyway), but from my understanding, Asterisk will be able to put whatever callerid desired. _______________________________________________ Asterisk-Biz mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-biz
