Trusted CallerID

From ITUwiki

CallerID is a service provider offering whereby the authoritative attributes of a calling party identifier are obtained and provided to the called party - usually as part of the call setup. The term 'authoritative' in this context is effected through a real-time query to the Identity provider that assigned the identifier to the calling party. In some jurisdictions, non-profit solicitors are obligated to use CallerID in conjunction with the call. CallerID allows the customer to make an informed choice regarding the communication - that may be enhanced through the use of distinctive ringtones or automated call diversion capabilities. In some jurisdictions it may be a criminal offense to deliberately alter the authoritative CallerID identifier attributes.
