CNAM Subtype Support for ENUM Queries

CNAM, calling name, data is a string up to 15 ASCII characters of information associated with a specific calling party name. The Internet-draft, draft-ietf-enum-cnam-08.txt, registers the Enumservice 'pstndata' and subtype 'cnam' using the URI scheme 'pstndata:' to specify the return of CNAM data in ENUM responses. The Oracle® Enterprise Session Border Controller recognizes CNAM data returned via this mechanism. CNAM data is then inserted into the display name of the From: header in the original Request. If a P-Asserted-ID header is present in the original request, the CNAM data is inserted there as well.

CNAM data is identified by an ENUM response with service-type: E2U+pstndata:cnam

CNAM support is configured in the sip profile configuration element, which can then be applied to either a session agent, realm, or SIP interface.

The Oracle® Enterprise Session Border Controller can preform CNAM queries on the signaling message’s ingress or egress from the system by setting the cnam lookup direction parameter to either ingress or egress. If the CNAM lookup direction parameters are configured on both the ingress and egress sides of a call, the Oracle® Enterprise Session Border Controller will only preform the lookup on the ingress side of the call.
