ADR (Additional Data Repository)
An ADR (Additional Data Repository) is a data storage facility for Additional Data. The ADR dereferences a URI passed in a SIP Call-Info header field or PIDF-LO provided-by element and returns an Additional Data object block. It replaces and deprecates the concept of CIDB (Call Information Database) previously defined in NENA-STA-010.
