This Recommendation describes an LDAP directory services architecture for multimedia conferencing using SIP. In particular, it defines an LDAP schema to represent SIP User Agents (UAs) on the network and associate those endpoints with users. This Recommendation is intended to supplement the CommObject directory architecture as discussed in ITU-T Rec. H.350, and not intended to be used as a stand-alone architecture. The implementation of this LDAP schema, together with the use of the H.350 CommObject architecture, facilitates the integration of SIP User Agents and conferencing devices into existing Enterprise Directories, thus allowing the user to perform white page lookups and access clickable dialling supported by SIP devices. The primary reasons for implementing this schema are identical to those listed in ITU-T Rec. H.350 (the CommObject class definition) as they apply specifically to the use of SIP UAs. |
