In addition this document registers the parameter “cnam” in the IANA “tel” Parameter Registry defined in RFCXXX. This data is used to facilitate the transfer of Calling Name Delivery (CNAM) data for calls that originate on the PSTN that may be displayed on VoIP or other Real-time Client User Agents (CUA).},
