This Recommendation 1 describes a simple lightweight directory access protocol (LDAP) and ITU-T X.500 schemas to represent call forwarding and call preference information in an ITU-T H.350 directory. It is intended to represent addresses to which calls should be forwarded in the case that an endpoint does not answer a call. It can direct calls to simple ITU-T H.320, ITU-T H.323 or session initiation protocol (SIP) addresses, or complex forwarding schemes such as time of day preferences, web pages, electronic mail or other applications. Implementers should review [ITU-T H.350] in detail before proceeding with this Recommendation.
