scope:

This enhanced Calling Name (eCNAM) standard describes the delivery of a calling name longer than 15 characters along with additional identifiers of the caller to eCNAM subscribers1 in the NGN. This Standard focuses on service offerings where: (a) both calling and called parties are in the IP-based NGN network, and (b) the Name and related information are obtained from a database. This North American standard delivers names in the extended ASCII set2 supporting English and French characters. Delivery of eCNAM in other languages is for future consideration.

This document treats multiple aspects of the eCNAM service, including end user perspective, database content, and the database access methods. However, issues related to the integrity of the caller's number are outside the scope of this standard. Telecom service providers (SPs) are investigating verification solutions to increase the reliability and authenticity of the delivered calling numbers which would help reduce the number of erroneous names being delivered.
